+ * Features: + *

    + *
  • allows null elements
    • + *
  • is immutable
    • + *
  • is thread-safe
    • + *
  • iterates in the order, in which elements were inserted
    • + *
+ *

+ * Performance characteristics: + *

    + *
  • copyAdd: O(1) amortized
    • + *
  • copyRemove: O(1)
    • + *
  • contains: O(1)
    • + *
  • toMutable: O(1) + a cost distributed across subsequent updates in the mutable copy
    • + *
  • clone: O(1)
    • + *
  • iterator.next(): O(log N)
    • + *
  • getFirst(), getLast(): O(N)
    • + *
+ *

+ * Implementation details: + *

+ * This set performs read and write operations of single elements in O(1) time, + * and in O(1) space. + *

+ * The CHAMP tree contains nodes that may be shared with other sets. + *

+ * If a write operation is performed on a node, then this set creates a + * copy of the node and of all parent nodes up to the root (copy-path-on-write). + * Since the CHAMP tree has a fixed maximal height, the cost is O(1). + *

+ * This set can create a mutable copy of itself in O(1) time and O(0) space + * using method {@link #toMutable()}}. The mutable copy shares its nodes + * with this set, until it has gradually replaced the nodes with exclusively + * owned nodes. + *

+ * Insertion Order: + *

+ * This set uses a counter to keep track of the insertion order. + * It stores the current value of the counter in the sequence number + * field of each data entry. If the counter wraps around, it must renumber all + * sequence numbers. + *

+ * The renumbering is why the {@code add} is O(1) only in an amortized sense. + *

+ * The iterator of the set is a priority queue, that orders the entries by + * their stored insertion counter value. This is why {@code iterator.next()} + * is O(log n). + *

+ * Features: + *

    + *
  • allows null elements
    • + *
  • is mutable
    • + *
  • is not thread-safe
    • + *
  • does not guarantee a specific iteration order
    • + *
+ *

+ * Performance characteristics: + *

    + *
  • add: O(1)
    • + *
  • remove: O(1)
    • + *
  • contains: O(1)
    • + *
  • toImmutable: O(1) + a cost distributed across subsequent updates in + * this set
    • + *
  • clone: O(1) + a cost distributed across subsequent updates in this + * set and in the clone
    • + *
  • iterator.next: O(log N)
    • + *
  • getFirst, getLast: O(N)
    • + *
+ *

+ * Implementation details: + *

+ * This set performs read and write operations of single elements in O(1) time, + * and in O(1) space. + *

+ * The CHAMP tree contains nodes that may be shared with other sets, and nodes + * that are exclusively owned by this set. + *

+ * If a write operation is performed on an exclusively owned node, then this + * set is allowed to mutate the node (mutate-on-write). + * If a write operation is performed on a potentially shared node, then this + * set is forced to create an exclusive copy of the node and of all not (yet) + * exclusively owned parent nodes up to the root (copy-path-on-write). + * Since the CHAMP tree has a fixed maximal height, the cost is O(1) in either + * case. + *

+ * This set can create an immutable copy of itself in O(1) time and O(0) space + * using method {@link #toImmutable()}. This set loses exclusive ownership of + * all its tree nodes. + * Thus, creating an immutable copy increases the constant cost of + * subsequent writes, until all shared nodes have been gradually replaced by + * exclusively owned nodes again. + *

+ * Note that this implementation is not synchronized. + * If multiple threads access this set concurrently, and at least + * one of the threads modifies the set, it must be synchronized + * externally. This is typically accomplished by synchronizing on some + * object that naturally encapsulates the set. + *

+ * Features: + *

    + *
  • allows null keys and null values
    • + *
  • is immutable
    • + *
  • is thread-safe
    • + *
  • does not guarantee a specific iteration order
    • + *
+ *

+ * Performance characteristics: + *

    + *
  • copyPut: O(1)
    • + *
  • copyRemove: O(1)
    • + *
  • containsKey: O(1)
    • + *
  • toMutable: O(1) + a cost distributed across subsequent updates in the mutable copy
    • + *
  • clone: O(1)
    • + *
  • iterator.next(): O(1)
    • + *
+ *

+ * Implementation details: + *

+ * This map performs read and write operations of single elements in O(1) time, + * and in O(1) space. + *

+ * The CHAMP tree contains nodes that may be shared with other maps. + *

+ * If a write operation is performed on a node, then this map creates a + * copy of the node and of all parent nodes up to the root (copy-path-on-write). + * Since the CHAMP tree has a fixed maximal height, the cost is O(1). + *

+ * This map can create a mutable copy of itself in O(1) time and O(1) space + * using method {@link #toMutable()}}. The mutable copy shares its nodes + * with this map, until it has gradually replaced the nodes with exclusively + * owned nodes. + *

+ * All operations on this set can be performed concurrently, without a need for + * synchronisation. + *

    + * Features: + *

      + *
    • allows null keys and null values
      • + *
    • is mutable
      • + *
    • is not thread-safe
      • + *
    • does not guarantee a specific iteration order
      • + *
    + *

    + * Performance characteristics: + *

      + *
    • put: O(1)
      • + *
    • remove: O(1)
      • + *
    • containsKey: O(1)
      • + *
    • toImmutable: O(1) + a cost distributed across subsequent updates in + * this map
      • + *
    • clone: O(1) + a cost distributed across subsequent updates in this + * map and in the clone
      • + *
    • iterator.next: O(1)
      • + *
    + *

    + * Implementation details: + *

    + * This map performs read and write operations of single elements in O(1) time, + * and in O(1) space. + *

    + * The CHAMP tree contains nodes that may be shared with other maps, and nodes + * that are exclusively owned by this map. + *

    + * If a write operation is performed on an exclusively owned node, then this + * map is allowed to mutate the node (mutate-on-write). + * If a write operation is performed on a potentially shared node, then this + * map is forced to create an exclusive copy of the node and of all not (yet) + * exclusively owned parent nodes up to the root (copy-path-on-write). + * Since the CHAMP tree has a fixed maximal height, the cost is O(1) in either + * case. + *

    + * This map can create an immutable copy of itself in O(1) time and O(1) space + * using method {@link #toImmutable()}. This map loses exclusive ownership of + * all its tree nodes. + * Thus, creating an immutable copy increases the constant cost of + * subsequent writes, until all shared nodes have been gradually replaced by + * exclusively owned nodes again. + *

    + * Features: + *

      + *
    • allows null keys and null values
      • + *
    • is immutable
      • + *
    • is thread-safe
      • + *
    • iterates in the order, in which keys were inserted
      • + *
    + *

    + * Performance characteristics: + *

      + *
    • copyPut, copyPutFirst, copyPutLast: O(1) amortized due to + * renumbering
      • + *
    • copyRemove: O(1) amortized due to renumbering
      • + *
    • containsKey: O(1)
      • + *
    • toMutable: O(1) + a cost distributed across subsequent updates in + * the mutable copy
      • + *
    • clone: O(1)
      • + *
    • iterator creation: O(N)
      • + *
    • iterator.next: O(1) with bucket sort or O(log N) with a heap
      • + *
    • getFirst, getLast: O(N)
      • + *
    + *

    + * Implementation details: + *

    + * This map performs read and write operations of single elements in O(1) time, + * and in O(1) space. + *

    + * The CHAMP tree contains nodes that may be shared with other maps. + *

    + * If a write operation is performed on a node, then this map creates a + * copy of the node and of all parent nodes up to the root (copy-path-on-write). + * Since the CHAMP tree has a fixed maximal height, the cost is O(1). + *

    + * This map can create a mutable copy of itself in O(1) time and O(1) space + * using method {@link #toMutable()}}. The mutable copy shares its nodes + * with this map, until it has gradually replaced the nodes with exclusively + * owned nodes. + *

    + * All operations on this set can be performed concurrently, without a need for + * synchronisation. + *

    + * Insertion Order: + *

    + * This map uses a counter to keep track of the insertion order. + * It stores the current value of the counter in the sequence number + * field of each data entry. If the counter wraps around, it must renumber all + * sequence numbers. + *

    + * The renumbering is why the {@code copyPut} is O(1) only in an amortized sense. + *

    + * The iterator of the map is a priority queue, that orders the entries by + * their stored insertion counter value. This is why {@code iterator.next()} + * is O(log n). + *

    + * Features: + *

      + *
    • allows null keys and null values
      • + *
    • is mutable
      • + *
    • is not thread-safe
      • + *
    • iterates in the order, in which keys were inserted
      • + *
    + *

    + * Performance characteristics: + *

      + *
    • put, putFirst, putLast: O(1) amortized due to renumbering
      • + *
    • remove: O(1)
      • + *
    • containsKey: O(1)
      • + *
    • toImmutable: O(1) + a cost distributed across subsequent updates in + * this mutable map
      • + *
    • clone: O(1) + a cost distributed across subsequent updates in this + * mutable map and in the clone
      • + *
    • iterator creation: O(N)
      • + *
    • iterator.next: O(1) with bucket sort or O(log N) with a heap
      • + *
    • getFirst, getLast: O(N)
      • + *
    + *

    + * Implementation details: + *

    + * This map performs read and write operations of single elements in O(1) time, + * and in O(1) space. + *

    + * The CHAMP tree contains nodes that may be shared with other maps, and nodes + * that are exclusively owned by this map. + *

    + * If a write operation is performed on an exclusively owned node, then this + * map is allowed to mutate the node (mutate-on-write). + * If a write operation is performed on a potentially shared node, then this + * map is forced to create an exclusive copy of the node and of all not (yet) + * exclusively owned parent nodes up to the root (copy-path-on-write). + * Since the CHAMP tree has a fixed maximal height, the cost is O(1) in either + * case. + *

    + * This map can create an immutable copy of itself in O(1) time and O(1) space + * using method {@link #toImmutable()}. This map loses exclusive ownership of + * all its tree nodes. + * Thus, creating an immutable copy increases the constant cost of + * subsequent writes, until all shared nodes have been gradually replaced by + * exclusively owned nodes again. + *

    + * Insertion Order: + *

    + * This map uses a counter to keep track of the insertion order. + * It stores the current value of the counter in the sequence number + * field of each data entry. If the counter wraps around, it must renumber all + * sequence numbers. + *

    + * The renumbering is why the {@code copyPut} is O(1) only in an amortized sense. + *

    + * The iterator of the map is a priority queue, that orders the entries by + * their stored insertion counter value. This is why {@code iterator.next()} + * is O(log n). + *

-[![vavr-logo](https://user-images.githubusercontent.com/743833/62367542-486f0500-b52a-11e9-815e-e9788d4c8c8d.png)](http://vavr.io/) +## Status -Vavr is an object-functional language extension to Java 8, which aims to reduce the lines of code and increase code quality. -It provides persistent collections, functional abstractions for error handling, concurrent programming, pattern matching and much more. +This is an experimental fork of [github.com/vavr-io/vavr](https://github.com/vavr-io/vavr). -Vavr fuses the power of object-oriented programming with the elegance and robustness of functional programming. -The most interesting part is a feature-rich, persistent collection library that smoothly integrates with Java's standard collections. +## CHAMP collections -Because Vavr does not depend on any libraries (other than the JVM) you can easily add it as standalone .jar to your classpath. +This fork contains additional collections, that use +CHAMP (Compressed Hash-Array Mapped Prefix-tree) as their underlying data structures. +The collections are derived from [github.com/usethesource/capsule](https://github.com/usethesource/capsule), +and [github.com/wrandelshofer/jhotdraw8](https://github.com/wrandelshofer/jhotdraw8). -To stay up to date please follow the [blog](http://blog.vavr.io). +The collections are: -## Using Vavr +* ChampSet +* ChampMap +* LinkedChampSet +* LinkedChampMap -See [User Guide](http://docs.vavr.io) and/or [Javadoc](http://www.javadoc.io/doc/io.vavr/vavr). +Each collection has a mutable partner: -### Gradle tasks:

subsequent updates of the mutable copy + +The costs are only constant in the limit. In practice, they are more like +O(log32 N). + +If a collection is converted from/to immutable/mutable, the mutual copy +of the collection loses ownership of all its trie nodes. Updates are slightly +more expensive for the mutual copy, until it gains exclusive ownership of all trie +nodes again. + +### LinkedChampSet, LinkedChampMap, MutableLinkedChampSet, MutableLinkedChampMap: + +* Maximal supported size: 230 elements. +* Get/Insert/Remove: O(1) amortized +* Head/Tail: O(N) +* Iterator creation: O(N) +* Iterator.next(): O(1) +* toImmutable/toMutable: O(1) + a cost distributed across subsequent updates of the mutable copy + +The collections are not actually linked.

The bucket sort is O(N) and not O(N log N). +We allocate enough buckets, so that we only need to store at most one sequence number +per bucket. + +Currently, the code contains a fall-back code for collections that grow larger than +230 elements. For very large collections the buckets do not fit into +a Java array anymore. We have to fall back to a heap. +With the heap, Iterator.next() needs O(log N) instead of O(1). + +## Benchmarks + +The following chart shows a comparison of the CHAMP maps with vavr collections +and with Scala collections. Scala org.scala-lang:scala-library:2.13.8 was used. + +The collections have 1 million entries. + +![](BenchmarkChart.png) + +* **scala.HashMap** has a very competitive and balanced performance. + It uses a CHAMP trie as its underlying data structure. +* **scala.VectorMap** has also a very competitive performance, removal and addition + of entries is a bit slower than with most other collections. + It uses a radix-balanced finger tree (Vector) and a CHAMP trie as its + underlying data structure. +* **vavr.HashMap** has a very competitive and balanced performance. + It uses a HAMP trie as its underlying data structure. +* **vavr.LinkedHashMap** has competitive query times, but updates need linear time. + It uses a HAMP trie and a Banker's queue as its underlying data structure. +* **vavr.ChampMap** has a very competitive and balanced performance. + It uses a CHAMP trie as its underlying data structure. +* **vavr.LinkedChampMap** has competitive performance except for accesses to the + first/last entry. It uses a CHAMP trie and sequence numbers on the entries. -A small number of users have reported problems building Vavr.

    + * Features: + *

      + *
    • supports up to 230 elements
      • + *
    • allows null elements
      • + *
    • is immutable
      • + *
    • is thread-safe
      • + *
    • iterates in the order, in which elements were inserted
      • + *
    + *

    + * Performance characteristics: + *

      + *
    • copyAdd: O(1) amortized
      • + *
    • copyRemove: O(1)
      • + *
    • contains: O(1)
      • + *
    • toMutable: O(1) + O(log N) distributed across subsequent updates in the mutable copy
      • + *
    • clone: O(1)
      • + *
    • iterator creation: O(N)
      • + *
    • iterator.next: O(1) with bucket sort, O(log N) with heap sort
      • + *
    • getFirst(), getLast(): O(N)
      • + *
    + *

    + * Implementation details: + *

    + * This set performs read and write operations of single elements in O(1) time, + * and in O(1) space. + *

    + * The CHAMP tree contains nodes that may be shared with other sets. + *

    + * If a write operation is performed on a node, then this set creates a + * copy of the node and of all parent nodes up to the root (copy-path-on-write). + * Since the CHAMP tree has a fixed maximal height, the cost is O(1). + *

    + * This set can create a mutable copy of itself in O(1) time and O(1) space + * using method {@link #toMutable()}}. The mutable copy shares its nodes + * with this set, until it has gradually replaced the nodes with exclusively + * owned nodes. + *

    + * Insertion Order: + *

    + * This set uses a counter to keep track of the insertion order. + * It stores the current value of the counter in the sequence number + * field of each data entry. If the counter wraps around, it must renumber all + * sequence numbers. + *

    + * The renumbering is why the {@code add} is O(1) only in an amortized sense. + *

    + * The iterator of the set is a priority queue, that orders the entries by + * their stored insertion counter value. This is why {@code iterator.next()} + * is O(log n). + *

    + * The CHAMP trie contains nodes that may be shared with other sets, and nodes + * that are exclusively owned by this set. + *

    + * If a write operation is performed on an exclusively owned node, then this + * set is allowed to mutate the node (mutate-on-write). + * If a write operation is performed on a potentially shared node, then this + * set is forced to create an exclusive copy of the node and of all not (yet) + * exclusively owned parent nodes up to the root (copy-path-on-write). + * Since the CHAMP trie has a fixed maximal height, the cost is O(1) in either + * case. + *

    + * This set can create an immutable copy of itself in O(1) time and O(1) space + * using method {@link #toImmutable()}. This set loses exclusive ownership of + * all its tree nodes. + * Thus, creating an immutable copy increases the constant cost of + * subsequent writes, until all shared nodes have been gradually replaced by + * exclusively owned nodes again. + *

    + * Insertion Order: + *

    + * This set uses a counter to keep track of the insertion order. + * It stores the current value of the counter in the sequence number + * field of each data entry. If the counter wraps around, it must renumber all + * sequence numbers. + *

    + * The renumbering is why the {@code add} is O(1) only in an amortized sense. + *

    + * The iterator of the set is a priority queue, that orders the entries by + * their stored insertion counter value. This is why {@code iterator.next()} + * is O(log n). + *

    + * Note that this implementation is not synchronized. + * If multiple threads access this set concurrently, and at least + * one of the threads modifies the set, it must be synchronized + * externally. This is typically accomplished by synchronizing on some + * object that naturally encapsulates the set. + *

    + * Features: + *

      + *
    • supports up to 230 entries
      • + *
    • allows null keys and null values
      • + *
    • is immutable
      • + *
    • is thread-safe
      • + *
    • iterates in the order, in which keys were inserted
      • + *
    + *

    + * Performance characteristics: + *

      + *
    • copyPut, copyPutFirst, copyPutLast: O(1) amortized, due to + * renumbering
      • + *
    • copyRemove: O(1) amortized, due to renumbering
      • + *
    • containsKey: O(1)
      • + *
    • toMutable: O(1) + O(log N) distributed across subsequent updates in + * the mutable copy
      • + *
    • clone: O(1)
      • + *
    • iterator creation: O(1)
      • + *
    • iterator.next: O(1) with bucket sort, O(log N) with heap sort
      • + *
    • getFirst, getLast: O(1)
      • + *
    + *

    + * Implementation details: + *

    + * This map performs read and write operations of single elements in O(1) time, + * and in O(1) space. + *

    + * The CHAMP trie contains nodes that may be shared with other maps. + *

    + * If a write operation is performed on a node, then this map creates a + * copy of the node and of all parent nodes up to the root (copy-path-on-write). + * Since the CHAMP trie has a fixed maximal height, the cost is O(1). + *

    + * This map can create a mutable copy of itself in O(1) time and O(1) space + * using method {@link #toMutable()}}. The mutable copy shares its nodes + * with this map, until it has gradually replaced the nodes with exclusively + * owned nodes. + *

    + * All operations on this set can be performed concurrently, without a need for + * synchronisation. + *

    + * Insertion Order: + *

    + * This map uses a counter to keep track of the insertion order. + * It stores the current value of the counter in the sequence number + * field of each data entry. If the counter wraps around, it must renumber all + * sequence numbers. + *

    + * The renumbering is why the {@code put} and {@code remove} methods are + * O(1) only in an amortized sense. + *

    + *

    + * To support iteration, a second CHAMP trie is maintained. The second CHAMP + * trie has the same contents as the first. However, we use the sequence number + * for computing the hash code of an element. + *

    + * In this implementation, a hash code has a length of + * 32 bits, and is split up in little-endian order into 7 parts of + * 5 bits (the last part contains the remaining bits). + *

    + * We convert the sequence number to unsigned 32 by adding Integer.MIN_VALUE + * to it. And then we reorder its bits from + * 66666555554444433333222221111100 to 00111112222233333444445555566666. + *

    + * Features: + *

      + *
    • supports up to 230 entries
      • + *
    • allows null keys and null values
      • + *
    • is mutable
      • + *
    • is not thread-safe
      • + *
    • iterates in the order, in which keys were inserted
      • + *
    + *

    + * Performance characteristics: + *

      + *
    • put, putFirst, putLast: O(1) amortized, due to renumbering
      • + *
    • remove: O(1) amortized, due to renumbering
      • + *
    • containsKey: O(1)
      • + *
    • toImmutable: O(1) + O(log N) distributed across subsequent updates in + * this mutable map
      • + *
    • clone: O(1) + O(log N) distributed across subsequent updates in this + * mutable map and in the clone
      • + *
    • iterator creation: O(1)
      • + *
    • iterator.next: O(1) with bucket sort, O(log N) with heap sort
      • + *
    • getFirst, getLast: O(1)
      • + *
    + *

    + * Implementation details: + *

    + * This map performs read and write operations of single elements in O(1) time, + * and in O(1) space. + *

    + * The CHAMP trie contains nodes that may be shared with other maps, and nodes + * that are exclusively owned by this map. + *

    + * If a write operation is performed on an exclusively owned node, then this + * map is allowed to mutate the node (mutate-on-write). + * If a write operation is performed on a potentially shared node, then this + * map is forced to create an exclusive copy of the node and of all not (yet) + * exclusively owned parent nodes up to the root (copy-path-on-write). + * Since the CHAMP trie has a fixed maximal height, the cost is O(1) in either + * case. + *

    + * This map can create an immutable copy of itself in O(1) time and O(1) space + * using method {@link #toImmutable()}. This map loses exclusive ownership of + * all its tree nodes. + * Thus, creating an immutable copy increases the constant cost of + * subsequent writes, until all shared nodes have been gradually replaced by + * exclusively owned nodes again. + *

    + * Insertion Order: + *

    + * This map uses a counter to keep track of the insertion order. + * It stores the current value of the counter in the sequence number + * field of each data entry. If the counter wraps around, it must renumber all + * sequence numbers. + *

    + * The renumbering is why the {@code put} and {@code remove} methods are + * O(1) only in an amortized sense. + *

    + * To support iteration, a second CHAMP trie is maintained. The second CHAMP + * trie has the same contents as the first. However, we use the sequence number + * for computing the hash code of an element. + *

    + * In this implementation, a hash code has a length of + * 32 bits, and is split up in little-endian order into 7 parts of + * 5 bits (the last part contains the remaining bits). + *

    + * We convert the sequence number to unsigned 32 by adding Integer.MIN_VALUE + * to it. And then we reorder its bits from + * 66666555554444433333222221111100 to 00111112222233333444445555566666. + *

    - * Implementation details: - *

    - * This map performs read and write operations of single elements in O(1) time, - * and in O(1) space. - *

    - * The CHAMP tree contains nodes that may be shared with other maps. - *

    - * If a write operation is performed on a node, then this map creates a - * copy of the node and of all parent nodes up to the root (copy-path-on-write). - * Since the CHAMP tree has a fixed maximal height, the cost is O(1). - *

    - * This map can create a mutable copy of itself in O(1) time and O(1) space - * using method {@link #toMutable()}}. The mutable copy shares its nodes - * with this map, until it has gradually replaced the nodes with exclusively - * owned nodes. - *

    - * All operations on this set can be performed concurrently, without a need for - * synchronisation. - *

    - * Insertion Order: - *

    - * This map uses a counter to keep track of the insertion order. - * It stores the current value of the counter in the sequence number - * field of each data entry. If the counter wraps around, it must renumber all - * sequence numbers. - *

    - * The renumbering is why the {@code copyPut} is O(1) only in an amortized sense. - *

    - * The iterator of the map is a priority queue, that orders the entries by - * their stored insertion counter value. This is why {@code iterator.next()} - * is O(log n). - *

    - * Features: - *

      - *
    • supports up to 230 elements
      • - *
    • allows null elements
      • - *
    • is immutable
      • - *
    • is thread-safe
      • - *
    • iterates in the order, in which elements were inserted
      • - *
    - *

    - * Performance characteristics: - *

      - *
    • copyAdd: O(1) amortized
      • - *
    • copyRemove: O(1)
      • - *
    • contains: O(1)
      • - *
    • toMutable: O(1) + O(log N) distributed across subsequent updates in the mutable copy
      • - *
    • clone: O(1)
      • - *
    • iterator creation: O(N)
      • - *
    • iterator.next: O(1) with bucket sort, O(log N) with heap sort
      • - *
    • getFirst(), getLast(): O(N)
      • - *
    - *

    - * Implementation details: - *

    - * This set performs read and write operations of single elements in O(1) time, - * and in O(1) space. - *

    - * The CHAMP tree contains nodes that may be shared with other sets. - *

    - * If a write operation is performed on a node, then this set creates a - * copy of the node and of all parent nodes up to the root (copy-path-on-write). - * Since the CHAMP tree has a fixed maximal height, the cost is O(1). - *

    - * This set can create a mutable copy of itself in O(1) time and O(1) space - * using method {@link #toMutable()}}. The mutable copy shares its nodes - * with this set, until it has gradually replaced the nodes with exclusively - * owned nodes. - *

    - * Insertion Order: - *

    - * This set uses a counter to keep track of the insertion order. - * It stores the current value of the counter in the sequence number - * field of each data entry. If the counter wraps around, it must renumber all - * sequence numbers. - *

    - * The renumbering is why the {@code add} is O(1) only in an amortized sense. - *

    - * The iterator of the set is a priority queue, that orders the entries by - * their stored insertion counter value. This is why {@code iterator.next()} - * is O(log n). - *

    - * Implementation details: - *

    - * This map performs read and write operations of single elements in O(1) time, - * and in O(1) space. - *

    - * The CHAMP tree contains nodes that may be shared with other maps, and nodes - * that are exclusively owned by this map. - *

    - * If a write operation is performed on an exclusively owned node, then this - * map is allowed to mutate the node (mutate-on-write). - * If a write operation is performed on a potentially shared node, then this - * map is forced to create an exclusive copy of the node and of all not (yet) - * exclusively owned parent nodes up to the root (copy-path-on-write). - * Since the CHAMP tree has a fixed maximal height, the cost is O(1) in either - * case. - *

    - * This map can create an immutable copy of itself in O(1) time and O(1) space - * using method {@link #toImmutable()}. This map loses exclusive ownership of - * all its tree nodes. - * Thus, creating an immutable copy increases the constant cost of - * subsequent writes, until all shared nodes have been gradually replaced by - * exclusively owned nodes again. - *

    - * Insertion Order: - *

    - * This map uses a counter to keep track of the insertion order. - * It stores the current value of the counter in the sequence number - * field of each data entry. If the counter wraps around, it must renumber all - * sequence numbers. - *

    - * The renumbering is why the {@code copyPut} is O(1) only in an amortized sense. - *

    - * The iterator of the map is a priority queue, that orders the entries by - * their stored insertion counter value. This is why {@code iterator.next()} - * is O(log n). - *

    + * Features: + *

      + *
    • supports up to 230 entries
      • + *
    • allows null keys and null values
      • + *
    • is immutable
      • + *
    • is thread-safe
      • + *
    • does not guarantee a specific iteration order
      • + *
    + *

    + * Performance characteristics: + *

      + *
    • copyPut: O(1)
      • + *
    • copyRemove: O(1)
      • + *
    • containsKey: O(1)
      • + *
    • toMutable: O(1) + O(log N) distributed across subsequent updates in the mutable copy
      • + *
    • clone: O(1)
      • + *
    • iterator.next(): O(1)
      • + *
    + *

    + * Implementation details: + *

    + * This map performs read and write operations of single elements in O(1) time, + * and in O(1) space. + *

    + * The CHAMP tree contains nodes that may be shared with other maps. + *

    + * If a write operation is performed on a node, then this map creates a + * copy of the node and of all parent nodes up to the root (copy-path-on-write). + * Since the CHAMP tree has a fixed maximal height, the cost is O(1). + *

    + * This map can create a mutable copy of itself in O(1) time and O(1) space + * using method {@link #toMutable()}}. The mutable copy shares its nodes + * with this map, until it has gradually replaced the nodes with exclusively + * owned nodes. + *

    + * All operations on this set can be performed concurrently, without a need for + * synchronisation. + *

    + * Features: + *

      + *
    • supports up to 230 elements
      • + *
    • allows null elements
      • + *
    • is immutable
      • + *
    • is thread-safe
      • + *
    • does not guarantee a specific iteration order
      • + *
    + *

    + * Performance characteristics: + *

      + *
    • add: O(1)
      • + *
    • remove: O(1)
      • + *
    • contains: O(1)
      • + *
    • toMutable: O(1) + O(log N) distributed across subsequent updates in the mutable copy
      • + *
    • clone: O(1)
      • + *
    • iterator.next(): O(1)
      • + *
    + *

    + * Implementation details: + *

    + * This set performs read and write operations of single elements in O(1) time, + * and in O(1) space. + *

    + * The CHAMP tree contains nodes that may be shared with other sets. + *

    + * If a write operation is performed on a node, then this set creates a + * copy of the node and of all parent nodes up to the root (copy-path-on-write). + * Since the CHAMP tree has a fixed maximal height, the cost is O(1). + *

    + * This set can create a mutable copy of itself in O(1) time and O(1) space + * using method {@code #toMutable()}}. The mutable copy shares its nodes + * with this set, until it has gradually replaced the nodes with exclusively + * owned nodes. + *

    + * Features: + *

      + *
    • supports up to 230 entries
      • + *
    • allows null keys and null values
      • + *
    • is immutable
      • + *
    • is thread-safe
      • + *
    • iterates in the order, in which keys were inserted
      • + *
    + *

    + * Performance characteristics: + *

      + *
    • copyPut, copyPutFirst, copyPutLast: O(1) amortized, due to + * renumbering
      • + *
    • copyRemove: O(1) amortized, due to renumbering
      • + *
    • containsKey: O(1)
      • + *
    • toMutable: O(1) + O(log N) distributed across subsequent updates in + * the mutable copy
      • + *
    • clone: O(1)
      • + *
    • iterator creation: O(1)
      • + *
    • iterator.next: O(1) with bucket sort, O(log N) with heap sort
      • + *
    • getFirst, getLast: O(1)
      • + *
    + *

    + * Implementation details: + *

    + * This map performs read and write operations of single elements in O(1) time, + * and in O(1) space. + *

    + * The CHAMP trie contains nodes that may be shared with other maps. + *

    + * If a write operation is performed on a node, then this map creates a + * copy of the node and of all parent nodes up to the root (copy-path-on-write). + * Since the CHAMP trie has a fixed maximal height, the cost is O(1). + *

    + * This map can create a mutable copy of itself in O(1) time and O(1) space + * using method {@link #toMutable()}}. The mutable copy shares its nodes + * with this map, until it has gradually replaced the nodes with exclusively + * owned nodes. + *

    + * All operations on this set can be performed concurrently, without a need for + * synchronisation. + *

    + * Insertion Order: + *

    + * This map uses a counter to keep track of the insertion order. + * It stores the current value of the counter in the sequence number + * field of each data entry. If the counter wraps around, it must renumber all + * sequence numbers. + *

    + * The renumbering is why the {@code put} and {@code remove} methods are + * O(1) only in an amortized sense. + *

    + * To support iteration, a second CHAMP trie is maintained. The second CHAMP + * trie has the same contents as the first. However, we use the sequence number + * for computing the hash code of an element. + *

    + * In this implementation, a hash code has a length of + * 32 bits, and is split up in little-endian order into 7 parts of + * 5 bits (the last part contains the remaining bits). + *

    + * We convert the sequence number to unsigned 32 by adding Integer.MIN_VALUE + * to it. And then we reorder its bits from + * 66666555554444433333222221111100 to 00111112222233333444445555566666. + *

    + * Features: + *

      + *
    • supports up to 230 elements
      • + *
    • allows null elements
      • + *
    • is immutable
      • + *
    • is thread-safe
      • + *
    • iterates in the order, in which elements were inserted
      • + *
    + *

    + * Performance characteristics: + *

      + *
    • copyAdd: O(1) amortized due to + * * renumbering
      • + *
    • copyRemove: O(1) amortized due to + * * renumbering
      • + *
    • contains: O(1)
      • + *
    • toMutable: O(1) + O(log N) distributed across subsequent updates in the mutable copy
      • + *
    • clone: O(1)
      • + *
    • iterator creation: O(1)
      • + *
    • iterator.next: O(1)
      • + *
    • getFirst(), getLast(): O(1)
      • + *
    + *

    + * Implementation details: + *

    + * This set performs read and write operations of single elements in O(1) time, + * and in O(1) space. + *

    + * The CHAMP trie contains nodes that may be shared with other sets. + *

    + * If a write operation is performed on a node, then this set creates a + * copy of the node and of all parent nodes up to the root (copy-path-on-write). + * Since the CHAMP trie has a fixed maximal height, the cost is O(1). + *

    + * This set can create a mutable copy of itself in O(1) time and O(1) space + * using method {@link #toMutable()}}. The mutable copy shares its nodes + * with this set, until it has gradually replaced the nodes with exclusively + * owned nodes. + *

    + * Insertion Order: + *

    + * This set uses a counter to keep track of the insertion order. + * It stores the current value of the counter in the sequence number + * field of each data entry. If the counter wraps around, it must renumber all + * sequence numbers. + *

    + * The renumbering is why the {@code add} and {@code remove} methods are O(1) + * only in an amortized sense. + *

    + * To support iteration, a second CHAMP trie is maintained. The second CHAMP + * trie has the same contents as the first. However, we use the sequence number + * for computing the hash code of an element. + *

    + * In this implementation, a hash code has a length of + * 32 bits, and is split up in little-endian order into 7 parts of + * 5 bits (the last part contains the remaining bits). + *

    + * We convert the sequence number to unsigned 32 by adding Integer.MIN_VALUE + * to it. And then we reorder its bits from + * 66666555554444433333222221111100 to 00111112222233333444445555566666. + *

    - * A trie is a tree structure that stores a set of data objects; the - * path to a data object is determined by a bit sequence derived from the data - * object. - *

    - * In a CHAMP trie, the bit sequence is derived from the hash code of a data - * object. A hash code is a bit sequence with a fixed length. This bit sequence - * is split up into parts.

Instead of allocating a node for - * each data object, the data objects are stored directly in the ancestor node - * at which the path to the data object starts to become unique.

    - * If the hash code of a data object in the set is not unique, then it is - * stored in a {@link HashCollisionNode}, otherwise it is stored in a - * {@link BitmapIndexedNode}. Since the hash codes have a fixed length, - * all {@link HashCollisionNode}s are located at the same, maximal depth - * of the tree. - *

    - * In this implementation, a hash code has a length of - * {@value #HASH_CODE_LENGTH} bits, and is split up in little-endian order into parts of - * {@value #BIT_PARTITION_SIZE} bits (the last part contains the remaining bits). - * - * @param the type of the data objects that are stored in this trie - */ - abstract static class Node { - /** - * Represents no data. - * We can not use {@code null}, because we allow storing null-data in the - * trie. - */ - static final Object NO_DATA = new Object(); - static final int HASH_CODE_LENGTH = 32; - /** - * Bit partition size in the range [1,5]. - *

    - * Features: - *

      - *
    • supports up to 230 entries
      • - *
    • allows null keys and null values
      • - *
    • is immutable
      • - *
    • is thread-safe
      • - *
    • does not guarantee a specific iteration order
      • - *
    - *

    - * Performance characteristics: - *

      - *
    • copyPut: O(1)
      • - *
    • copyRemove: O(1)
      • - *
    • containsKey: O(1)
      • - *
    • toMutable: O(1) + O(log N) distributed across subsequent updates in the mutable copy
      • - *
    • clone: O(1)
      • - *
    • iterator.next(): O(1)
      • - *
    - *

    - * Implementation details: - *

    - * This map performs read and write operations of single elements in O(1) time, - * and in O(1) space. - *

    - * The CHAMP tree contains nodes that may be shared with other maps. - *

    - * If a write operation is performed on a node, then this map creates a - * copy of the node and of all parent nodes up to the root (copy-path-on-write). - * Since the CHAMP tree has a fixed maximal height, the cost is O(1). - *

    - * This map can create a mutable copy of itself in O(1) time and O(1) space - * using method {@link #toMutable()}}. The mutable copy shares its nodes - * with this map, until it has gradually replaced the nodes with exclusively - * owned nodes. - *

    - * Features: - *

      - *
    • supports up to 230 elements
      • - *
    • allows null elements
      • - *
    • is immutable
      • - *
    • is thread-safe
      • - *
    • does not guarantee a specific iteration order

    - * Performance characteristics: - *

      - *
    • add: O(1)
      • - *
    • remove: O(1)
      • - *
    • contains: O(1)
      • - *
    • toMutable: O(1) + O(log N) distributed across subsequent updates in the mutable copy

    - * Implementation details: - *

    - * This set performs read and write operations of single elements in O(1) time, - * and in O(1) space. - *

    - * The CHAMP tree contains nodes that may be shared with other sets. - *

    - * If a write operation is performed on a node, then this set creates a - * copy of the node and of all parent nodes up to the root (copy-path-on-write). - * Since the CHAMP tree has a fixed maximal height, the cost is O(1). - *

    - * Implementation details: - *

    - * This map performs read and write operations of single elements in O(1) time, - * and in O(1) space. - *

    - * The CHAMP trie contains nodes that may be shared with other maps. - *

    - * If a write operation is performed on a node, then this map creates a - * copy of the node and of all parent nodes up to the root (copy-path-on-write). - * Since the CHAMP trie has a fixed maximal height, the cost is O(1). - *

    - * This map can create a mutable copy of itself in O(1) time and O(1) space - * using method {@link #toMutable()}}. The mutable copy shares its nodes - * with this map, until it has gradually replaced the nodes with exclusively - * owned nodes. - *

    - * All operations on this set can be performed concurrently, without a need for - * synchronisation. - *

    - * Insertion Order: - *

    - * This map uses a counter to keep track of the insertion order. - * It stores the current value of the counter in the sequence number - * field of each data entry. If the counter wraps around, it must renumber all - * sequence numbers. - *

    - * The renumbering is why the {@code put} and {@code remove} methods are - * O(1) only in an amortized sense. - *

    - * To support iteration, a second CHAMP trie is maintained. The second CHAMP - * trie has the same contents as the first. However, we use the sequence number - * for computing the hash code of an element. - *

    - * In this implementation, a hash code has a length of - * 32 bits, and is split up in little-endian order into 7 parts of - * 5 bits (the last part contains the remaining bits). - *

    - * We convert the sequence number to unsigned 32 by adding Integer.MIN_VALUE - * to it. And then we reorder its bits from - * 66666555554444433333222221111100 to 00111112222233333444445555566666. - *

Subject: [PATCH 050/169] WIP: Replace internal representation of HashSet by a
 CHAMP trie.

Changes:

build.gradle
- Temporarily raises Java version from 8 to 17, because we are porting code from JHotDraw 8 which is on 17. We intend to change this back to Java 8.

ChampAbstractChampSpliterator.java,
ChampAbstractTransientChampSet.java,
ChampBitmapIndexedNode.java,
ChampChangeEvent.java,
ChampHashCollisionNode.java,
ChampIdentityObject.java,
ChampIteratorAdapter.java,
ChampListHelper.java,
ChampMutableBitmapIndexedNode.java,
ChampMutableHashCollisionNode.java,
ChampNode.java,
ChampNodeFactory.java,
ChampSequencedData.java,
ChampSequencedElement.java,
ChampSequencedEntry.java,
ChampSequencedVectorSpliterator.java,
ChampSpliterator.java,
ChampTombstone.java
- Classes with prefix "Champ" provide the CHAMP trie data structure and operations that act on it.
- Maybe we lump them all together into a ChampTrie class (similar to BitMappedTrie). However, for now, it is much easier to have separate source files for each class.

HashSet.java
- Replaces its internal representation from HashArrayMappedTrie to a CHAMP trie.
- This class extends from ChampBitmapIndexedNode rather than using composition. This helps to reduce memory usage for small collections (we save 16 bytes), and this improves the performance (we save one level of indirection).

+ * A trie is a tree structure that stores a set of data objects; the
+ * path to a data object is determined by a bit sequence derived from the data
+ * object.
+ * 
    
+ * In a CHAMP trie, the bit sequence is derived from the hash code of a data
+ * object. A hash code is a bit sequence with a fixed length. This bit sequence
+ * is split up into parts. Each part is used as the index to the next child node
+ * in the tree, starting from the root node of the tree.
+ * 
    
+ * The nodes of a CHAMP trie are compressed. Instead of allocating a node for
+ * each data object, the data objects are stored directly in the ancestor node
+ * at which the path to the data object starts to become unique. This means,
+ * that in most cases, only a prefix of the bit sequence is needed for the
+ * path to a data object in the tree.
+ * 
    
+ * If the hash code of a data object in the set is not unique, then it is
+ * stored in a {@link ChampHashCollisionNode}, otherwise it is stored in a
+ * {@link ChampBitmapIndexedNode}. Since the hash codes have a fixed length,
+ * all {@link ChampHashCollisionNode}s are located at the same, maximal depth
+ * of the tree.
+ * 
    
+ * In this implementation, a hash code has a length of
+ * {@value #HASH_CODE_LENGTH} bits, and is split up in little-endian order into parts of
+ * {@value #BIT_PARTITION_SIZE} bits (the last part contains the remaining bits).

Subject: [PATCH 053/169] WIP: Replace internal representation of HashMap by a
 CHAMP trie.

Changes:

HashMap.java
- Replaces its internal representation from HashArrayMappedTrie to a CHAMP trie.

ChampChangeEvent.java
- Adds method isAdded().

HashSet.java
- Adds javadoc.
- Renames method updateFunction to updateElement.

HashMapTest.java
- Changes the expected result of 2 unit tests. I believe, that the test expectations were wrong.

      • 
+ * 
    
+ * 
    
+ * Implementation details:
+ * 
    
+ * This map performs read and write operations of single elements in O(1) time,
+ * and in O(1) space.
+ * 
    
+ * The CHAMP trie contains nodes that may be shared with other maps.
+ * 
    
+ * If a write operation is performed on a node, then this map creates a
+ * copy of the node and of all parent nodes up to the root (copy-path-on-write).
+ * Since the CHAMP trie has a fixed maximal height, the cost is O(1).
+ * 
    
+ * All operations on this map can be performed concurrently, without a need for
+ * synchronisation.
+ * 
    
+ * The immutable version of this map extends from the non-public class
+ * {@code ChampBitmapIndexNode}. This design safes 16 bytes for every instance,
+ * and reduces the number of redirections for finding an element in the
+ * collection by 1.
+ *

 /**
- * An immutable {@code HashSet} implementation.
+ * Implements an immutable set using a Compressed Hash-Array Mapped Prefix-tree
+ * (CHAMP).
+ * 
    
+ * Features:
+ * 
      
+ *     
    • supports up to 230 entries
      • 
+ *     
    • allows null elements
      • 
+ *     
    • is immutable
      • 
+ *     
    • is thread-safe
      • 
+ *     
    • does not guarantee a specific iteration order
      • 
+ * 
    
+ * 
    
+ * Performance characteristics:
+ * 
      
+ *     
    • add: O(1)
      • 
+ *     
    • remove: O(1)
      • 
+ *     
    • contains: O(1)
      • 
+ *     
    • toMutable: O(1) + O(log N) distributed across subsequent updates in the mutable copy
      • 
+ *     
    • clone: O(1)
      • 
+ *     
    • iterator.next(): O(1)
      • 
+ * 
    
+ * 
    
+ * Implementation details:
+ * 
    
+ * This set performs read and write operations of single elements in O(1) time,
+ * and in O(1) space.
+ * 
    
+ * The CHAMP trie contains nodes that may be shared with other sets.
+ * 
    
+ * If a write operation is performed on a node, then this set creates a
+ * copy of the node and of all parent nodes up to the root (copy-path-on-write).
+ * Since the CHAMP trie has a fixed maximal height, the cost is O(1).
+ * 
    
+ * The immutable version of this set extends from the non-public class
+ * {@code ChampBitmapIndexNode}. This design safes 16 bytes for every instance,
+ * and reduces the number of redirections for finding an element in the
+ * collection by 1.
+ * 
    
+ * References:
+ * 
    
+ * Portions of the code in this class have been derived from 'The Capsule Hash Trie Collections Library', and from
+ * 'JHotDraw 8'.

 /**
- * An immutable {@code HashSet} implementation that has predictable (insertion-order) iteration.
+ * Implements a mutable set using a Compressed Hash-Array Mapped Prefix-tree
+ * (CHAMP) and a bit-mapped trie (Vector).
+ * 
    
+ * Features:
+ * 
      
+ *     
    • supports up to 230 elements
      • 
+ *     
    • allows null elements
      • 
+ *     
    • is immutable
      • 
+ *     
    • is thread-safe
      • 
+ *     
    • iterates in the order, in which elements were inserted
      • 
+ * 
    
+ * 
    
+ * Performance characteristics:
+ * 
      
+ *     
    • add: O(log N) in an amortized sense, because we sometimes have to
+ *     renumber the elements.
      • 
+ *     
    • remove: O(log N) in an amortized sense, because we sometimes have to
+ *     renumber the elements.
      • 
+ *     
    • contains: O(1)
      • 
+ *     
    • toMutable: O(1) + O(log N) distributed across subsequent updates in
+ *     the mutable copy
      • 
+ *     
    • clone: O(1)
      • 
+ *     
    • iterator creation: O(1)
      • 
+ *     
    • iterator.next: O(log N)
      • 
+ *     
    • getFirst(), getLast(): O(log N)
      • 
+ * 
    
+ * 
    
+ * Implementation details:
+ * 
    
+ * This set performs read and write operations of single elements in O(log N) time,
+ * and in O(log N) space, where N is the number of elements in the set.
+ * 
    
+ * The CHAMP trie contains nodes that may be shared with other sets.
+ * 
    
+ * If a write operation is performed on a node, then this set creates a
+ * copy of the node and of all parent nodes up to the root (copy-path-on-write).
+ * Since the CHAMP trie has a fixed maximal height, the cost is O(1).
+ * 
    
+ * Insertion Order:
+ * 
    
+ * This set uses a counter to keep track of the insertion order.
+ * It stores the current value of the counter in the sequence number
+ * field of each data entry. If the counter wraps around, it must renumber all
+ * sequence numbers.
+ * 
    
+ * The renumbering is why the {@code add} and {@code remove} methods are O(1)
+ * only in an amortized sense.
+ * 
    
+ * To support iteration, we use a Vector. The Vector has the same contents
+ * as the CHAMP trie. However, its elements are stored in insertion order.
+ * 
    
+ * If an element is removed from the CHAMP trie that is not the first or the
+ * last element of the Vector, we replace its corresponding element in
+ * the Vector by a tombstone. If the element is at the start or end of the Vector,
+ * we remove the element and all its neighboring tombstones from the Vector.
+ * 
    
+ * A tombstone can store the number of neighboring tombstones in ascending and in descending
+ * direction. We use these numbers to skip tombstones when we iterate over the vector.
+ * Since we only allow iteration in ascending or descending order from one of the ends of
+ * the vector, we do not need to keep the number of neighbors in all tombstones up to date.
+ * It is sufficient, if we update the neighbor with the lowest index and the one with the
+ * highest index.
+ * 
    
+ * If the number of tombstones exceeds half of the size of the collection, we renumber all
+ * sequence numbers, and we create a new Vector.
+ * 
    
+ * The immutable version of this set extends from the non-public class
+ * {@code ChampBitmapIndexNode}. This design safes 16 bytes for every instance,
+ * and reduces the number of redirections for finding an element in the
+ * collection by 1.
+ * 
    
+ * References:
+ * 
    
+ * Portions of the code in this class has been derived from 'vavr' Vector.java.
+ * 
    
+ * The design of this class is inspired by 'VectorMap.scala'.

- * An immutable {@code LinkedHashMap} implementation that has predictable (insertion-order) iteration.

+ * Features:
+ * 
      
+ *     
    • supports up to 230 entries
      • 
+ *     
    • allows null keys and null values

+ *     
    • put, putFirst, putLast: O(log N) in an amortized sense, because we sometimes have to

+ * 
    
+ * Implementation details:
+ * 
    
+ * This map performs read and write operations of single elements in O(log N) time,
+ * and in O(log N) space, where N is the number of elements in the set.
+ * 
    
+ * The CHAMP trie contains nodes that may be shared with other maps.
+ * 
    
+ * If a write operation is performed on a node, then this set creates a
+ * copy of the node and of all parent nodes up to the root (copy-path-on-write).
+ * Since the CHAMP trie has a fixed maximal height, the cost is O(1).
+ * 
    
+ * Insertion Order:
+ * 
    
+ * This map uses a counter to keep track of the insertion order.
+ * It stores the current value of the counter in the sequence number
+ * field of each data entry. If the counter wraps around, it must renumber all
+ * sequence numbers.
+ * 
    
+ * The renumbering is why the {@code add} and {@code remove} methods are O(1)
+ * only in an amortized sense.
+ * 
    
+ * To support iteration, we use a Vector. The Vector has the same contents
+ * as the CHAMP trie. However, its elements are stored in insertion order.
+ * 
    
+ * If an element is removed from the CHAMP trie that is not the first or the
+ * last element of the Vector, we replace its corresponding element in
+ * the Vector by a tombstone. If the element is at the start or end of the Vector,
+ * we remove the element and all its neighboring tombstones from the Vector.
+ * 
    
+ * A tombstone can store the number of neighboring tombstones in ascending and in descending
+ * direction. We use these numbers to skip tombstones when we iterate over the vector.
+ * Since we only allow iteration in ascending or descending order from one of the ends of
+ * the vector, we do not need to keep the number of neighbors in all tombstones up to date.
+ * It is sufficient, if we update the neighbor with the lowest index and the one with the
+ * highest index.
+ * 
    
+ * If the number of tombstones exceeds half of the size of the collection, we renumber all
+ * sequence numbers, and we create a new Vector.
+ * 
    
+ * The immutable version of this set extends from the non-public class
+ * {@code ChampBitmapIndexNode}. This design safes 16 bytes for every instance,
+ * and reduces the number of redirections for finding an element in the
+ * collection by 1.

Subject: [PATCH 059/169] Add benchmarks. There appears to be a bug in
 transient 'update' methods in CHAMP trie nodes, because it is not faster than
 non-transient 'update'. Transient 'remove' in CHAMP trie nodes is faster than
 the non-transient 'remove' - so that seems to be correct.

-/**
- * Implements a mutable map using a Compressed Hash-Array Mapped Prefix-tree
- * (CHAMP).
- * 
    
- * Features:
- * 
      
- *     
    • supports up to 230 entries
      • 
- *     
    • allows null keys and null values
      • 
- *     
    • is mutable
      • 
- *     
    • is not thread-safe
      • 
- *     
    • does not guarantee a specific iteration order
      • 
- * 
    
- * 
    
- * Performance characteristics:
- * 
      
- *     
    • put: O(1)
      • 
- *     
    • remove: O(1)
      • 
- *     
    • containsKey: O(1)
      • 
- *     
    • toImmutable: O(1) + O(log N) distributed across subsequent updates in
- *     this map
      • 
- *     
    • clone: O(1) + O(log N) distributed across subsequent updates in this
- *     map and in the clone
      • 
- *     
    • iterator.next: O(1)
      • 
- * 
    
- * 
    
- * Implementation details:
- * 
    
- * This map performs read and write operations of single elements in O(1) time,
- * and in O(1) space.
- * 
    
- * The CHAMP tree contains nodes that may be shared with other maps, and nodes
- * that are exclusively owned by this map.
- * 
    
- * If a write operation is performed on an exclusively owned node, then this
- * map is allowed to mutate the node (mutate-on-write).
- * If a write operation is performed on a potentially shared node, then this
- * map is forced to create an exclusive copy of the node and of all not (yet)
- * exclusively owned parent nodes up to the root (copy-path-on-write).
- * Since the CHAMP tree has a fixed maximal height, the cost is O(1) in either
- * case.
- * 
    
- * This map can create an immutable copy of itself in O(1) time and O(1) space
- * using method {@link #toImmutable()}. This map loses exclusive ownership of
- * all its tree nodes.
- * Thus, creating an immutable copy increases the constant cost of
- * subsequent writes, until all shared nodes have been gradually replaced by
- * exclusively owned nodes again.
- *

- * Implements a mutable set using a Compressed Hash-Array Mapped Prefix-tree
- * (CHAMP).
- * 
    
- * Features:
- * 
      
- *     
    • supports up to 230 elements
      • 
- *     
    • allows null elements
      • 
- *     
    • is mutable
      • 
- *     
    • is not thread-safe
      • 
- *     
    • does not guarantee a specific iteration order
      • 
- * 
    
- * 
    
- * Performance characteristics:
- * 
      
- *     
    • add: O(1)
      • 
- *     
    • remove: O(1)
      • 
- *     
    • contains: O(1)
      • 
- *     
    • toImmutable: O(1) + O(log N) distributed across subsequent updates in
- *     this set
      • 
- *     
    • clone: O(1) + O(log N) distributed across subsequent updates in this
- *     set and in the clone
      • 
- *     
    • iterator.next: O(1)
      • 
- * 
    
- * 
    
- * Implementation details:
- * 
    
- * This set performs read and write operations of single elements in O(1) time,
- * and in O(1) space.
- * 
    
- * The CHAMP tree contains nodes that may be shared with other sets, and nodes
- * that are exclusively owned by this set.
- * 
    
- * If a write operation is performed on an exclusively owned node, then this
- * set is allowed to mutate the node (mutate-on-write).
- * If a write operation is performed on a potentially shared node, then this
- * set is forced to create an exclusive copy of the node and of all not (yet)
- * exclusively owned parent nodes up to the root (copy-path-on-write).
- * Since the CHAMP tree has a fixed maximal height, the cost is O(1) in either
- * case.
- * 
    
- * This set can create an immutable copy of itself in O(1) time and O(1) space
- * using method {@link #toImmutable()}. This set loses exclusive ownership of
- * all its tree nodes.
- * Thus, creating an immutable copy increases the constant cost of
- * subsequent writes, until all shared nodes have been gradually replaced by
- * exclusively owned nodes again.
- * 
    
- * Note that this implementation is not synchronized.
- * If multiple threads access this set concurrently, and at least
- * one of the threads modifies the set, it must be synchronized
- * externally.  This is typically accomplished by synchronizing on some
- * object that naturally encapsulates the set.

      • 
- *     
    • getFirst, getLast: O(1)
      • 
- * 
    
- * 
    
- * Implementation details:
- * 
    
- * This map performs read and write operations of single elements in O(1) time,
- * and in O(1) space.
- * 
    
- * The CHAMP trie contains nodes that may be shared with other maps, and nodes
- * that are exclusively owned by this map.
- * 
    
- * If a write operation is performed on an exclusively owned node, then this
- * map is allowed to mutate the node (mutate-on-write).
- * If a write operation is performed on a potentially shared node, then this
- * map is forced to create an exclusive copy of the node and of all not (yet)
- * exclusively owned parent nodes up to the root (copy-path-on-write).
- * Since the CHAMP trie has a fixed maximal height, the cost is O(1) in either
- * case.
- * 
    
- * This map can create an immutable copy of itself in O(1) time and O(1) space
- * using method {@link #toImmutable()}. This map loses exclusive ownership of
- * all its tree nodes.
- * Thus, creating an immutable copy increases the constant cost of
- * subsequent writes, until all shared nodes have been gradually replaced by
- * exclusively owned nodes again.
- * 
    
- * Insertion Order:
- * 
    
- * This map uses a counter to keep track of the insertion order.
- * It stores the current value of the counter in the sequence number
- * field of each data entry. If the counter wraps around, it must renumber all
- * sequence numbers.
- * 
    
- * The renumbering is why the {@code put} and {@code remove} methods are
- * O(1) only in an amortized sense.
- * 
    
- * To support iteration, a second CHAMP trie is maintained. The second CHAMP
- * trie has the same contents as the first. However, we use the sequence number
- * for computing the hash code of an element.
- * 
    
- * In this implementation, a hash code has a length of
- * 32 bits, and is split up in little-endian order into 7 parts of
- * 5 bits (the last part contains the remaining bits).
- * 
    
- * We convert the sequence number to unsigned 32 by adding Integer.MIN_VALUE
- * to it. And then we reorder its bits from
- * 66666555554444433333222221111100 to 00111112222233333444445555566666.

-/**
- * Implements a mutable set using a Compressed Hash-Array Mapped Prefix-tree
- * (CHAMP), with predictable iteration order.
- * 
    
- * Features:
- * 
      
- *     
    • supports up to 230 elements
      • 
- *     
    • allows null elements
      • 
- *     
    • is mutable
      • 
- *     
    • is not thread-safe
      • 
- *     
    • iterates in the order, in which elements were inserted
      • 
- * 
    
- * 
    
- * Performance characteristics:
- * 
      
- *     
    • add: O(1) amortized
      • 
- *     
    • remove: O(1)
      • 
- *     
    • contains: O(1)
      • 
- *     
    • toImmutable: O(1) + O(log N) distributed across subsequent updates in
- *     this set
      • 
- *     
    • clone: O(1) + O(log N) distributed across subsequent updates in this
- *     set and in the clone
      • 
- *     
    • iterator creation: O(1)
      • 
- *     
    • iterator.next: O(1) with bucket sort, O(log N) with heap sort
      • 
- *     
    • getFirst, getLast: O(1)
      • 
- * 
    
- * 
    
- * Implementation details:
- * 
    
- * This set performs read and write operations of single elements in O(1) time,
- * and in O(1) space.
- * 
    
- * The CHAMP trie contains nodes that may be shared with other sets, and nodes
- * that are exclusively owned by this set.
- * 
    
- * If a write operation is performed on an exclusively owned node, then this
- * set is allowed to mutate the node (mutate-on-write).
- * If a write operation is performed on a potentially shared node, then this
- * set is forced to create an exclusive copy of the node and of all not (yet)
- * exclusively owned parent nodes up to the root (copy-path-on-write).
- * Since the CHAMP trie has a fixed maximal height, the cost is O(1) in either
- * case.
- * 
    
- * This set can create an immutable copy of itself in O(1) time and O(1) space
- * using method {@link #toImmutable()}. This set loses exclusive ownership of
- * all its tree nodes.
- * Thus, creating an immutable copy increases the constant cost of
- * subsequent writes, until all shared nodes have been gradually replaced by
- * exclusively owned nodes again.
- * 
    
- * Insertion Order:
- * 
    
- * This set uses a counter to keep track of the insertion order.
- * It stores the current value of the counter in the sequence number
- * field of each data entry. If the counter wraps around, it must renumber all
- * sequence numbers.
- * 
    
- * The renumbering is why the {@code add} is O(1) only in an amortized sense.
- * 
    
- * To support iteration, a second CHAMP trie is maintained. The second CHAMP
- * trie has the same contents as the first. However, we use the sequence number
- * for computing the hash code of an element.
- * 
    
- * In this implementation, a hash code has a length of
- * 32 bits, and is split up in little-endian order into 7 parts of
- * 5 bits (the last part contains the remaining bits).
- * 
    
- * We convert the sequence number to unsigned 32 by adding Integer.MIN_VALUE
- * to it. And then we reorder its bits from
- * 66666555554444433333222221111100 to 00111112222233333444445555566666.
- * 
    
- * Note that this implementation is not synchronized.
- * If multiple threads access this set concurrently, and at least
- * one of the threads modifies the set, it must be synchronized
- * externally.  This is typically accomplished by synchronizing on some
- * object that naturally encapsulates the set.

- * Represents a node in a 'Compressed Hash-Array Mapped Prefix-tree'

- * 
    
- * A trie is a tree structure that stores a set of data objects; the
- * path to a data object is determined by a bit sequence derived from the data
- * object.
- * 
    
- * In a CHAMP trie, the bit sequence is derived from the hash code of a data
- * object. A hash code is a bit sequence with a fixed length. This bit sequence
- * is split up into parts. Each part is used as the index to the next child node
- * in the tree, starting from the root node of the tree.
- * 
    
- * The nodes of a CHAMP trie are compressed. Instead of allocating a node for
- * each data object, the data objects are stored directly in the ancestor node
- * at which the path to the data object starts to become unique. This means,
- * that in most cases, only a prefix of the bit sequence is needed for the
- * path to a data object in the tree.
- * 
    
- * If the hash code of a data object in the set is not unique, then it is
- * stored in a {@link HashCollisionNode}, otherwise it is stored in a
- * {@link BitmapIndexedNode}. Since the hash codes have a fixed length,
- * all {@link HashCollisionNode}s are located at the same, maximal depth
- * of the tree.
- * 
    
- * In this implementation, a hash code has a length of
- * {@value #HASH_CODE_LENGTH} bits, and is split up in little-endian order into parts of
- * {@value #BIT_PARTITION_SIZE} bits (the last part contains the remaining bits).

-/**
- * Represents a node in a 'Compressed Hash-Array Mapped Prefix-tree'
- * (CHAMP) trie.
- * 
    
- * A trie is a tree structure that stores a set of data objects; the
- * path to a data object is determined by a bit sequence derived from the data
- * object.
- * 
    
- * In a CHAMP trie, the bit sequence is derived from the hash code of a data
- * object. A hash code is a bit sequence with a fixed length. This bit sequence
- * is split up into parts. Each part is used as the index to the next child node
- * in the tree, starting from the root node of the tree.
- * 
    
- * The nodes of a CHAMP trie are compressed. Instead of allocating a node for
- * each data object, the data objects are stored directly in the ancestor node
- * at which the path to the data object starts to become unique. This means,
- * that in most cases, only a prefix of the bit sequence is needed for the
- * path to a data object in the tree.
- * 
    
- * If the hash code of a data object in the set is not unique, then it is
- * stored in a {@link ChampHashCollisionNode}, otherwise it is stored in a
- * {@link ChampBitmapIndexedNode}. Since the hash codes have a fixed length,
- * all {@link ChampHashCollisionNode}s are located at the same, maximal depth
- * of the tree.
- * 
    
- * In this implementation, a hash code has a length of
- * {@value #HASH_CODE_LENGTH} bits, and is split up in little-endian order into parts of
- * {@value #BIT_PARTITION_SIZE} bits (the last part contains the remaining bits).
- *

- * Uses a stack with a fixed maximal depth.
- * Iterates over keys in preorder sequence.

-/**
- * A tombstone is used by {@code VectorSet} to mark a deleted slot in its Vector.
- * 
    
- * A tombstone stores the minimal number of neighbors 'before' and 'after' it in the
- * Vector.
- * 
    
- * When we insert a new tombstone, we update 'before' and 'after' values only on
- * the first and last tombstone of a sequence of tombstones. Therefore, a delete
- * operation requires reading of up to 3 neighboring elements in the vector, and
- * updates of up to 3 elements.
- * 
    
- * There are no tombstones at the first and last element of the vector. When we
- * remove the first or last element of the vector, we remove the tombstones.
- * 
    
- * Example: Tombstones are shown as before.after.
- * 
    - *
- *
- *                              Indices:  0   1   2   3   4   5   6   7   8   9
- * Initial situation:           Values:  'a' 'b' 'c' 'd' 'e' 'f' 'g' 'h' 'i' 'j'
- *
- * Deletion of element 5:
- * - read elements at indices 4, 5, 6                    'e' 'f' 'g'
- * - notice that none of them are tombstones
- * - put tombstone 0.0 at index 5                            0.0
- *
- * After deletion of element 5:          'a' 'b' 'c' 'd' 'e' 0.0 'g' 'h' 'i' 'j'
- *
- * After deletion of element 7:          'a' 'b' 'c' 'd' 'e' 0.0 'g' 0.0 'i' 'j'
- *
- * Deletion of element 8:
- * - read elements at indices 7, 8, 9                                0.0 'i' 'j'
- * - notice that 7 is a tombstone 0.0
- * - put tombstones 0.1, 1.0 at indices 7 and 8
- *
- * After deletion of element 8:          'a' 'b' 'c' 'd' 'e' 0.0 'g' 0.1 1.0 'j'
- *
- * Deletion of element 6:
- * - read elements at indices 5, 6, 7                        0.0 'g' 0.1
- * - notice that two of them are tombstones
- * - put tombstones 0.3, 0.0, 3.0 at indices 5, 6 and 8
- *
- * After deletion of element 6:          'a' 'b' 'c' 'd' 'e' 0.3 0.0 0.1 3.0 'j'
- *
- * Deletion of the last element 9:
- * - read elements at index 8                                            3.0
- * - notice that it is a tombstone
- * - remove the last element and the neighboring tombstone sequence
- *

+     * A trie is a tree structure that stores a set of data objects; the
+     * path to a data object is determined by a bit sequence derived from the data
+     * object.
+     * 
    
+     * In a CHAMP trie, the bit sequence is derived from the hash code of a data
+     * object. A hash code is a bit sequence with a fixed length. This bit sequence
+     * is split up into parts. Each part is used as the index to the next child node
+     * in the tree, starting from the root node of the tree.
+     * 
    
+     * The nodes of a CHAMP trie are compressed. Instead of allocating a node for
+     * each data object, the data objects are stored directly in the ancestor node
+     * at which the path to the data object starts to become unique. This means,
+     * that in most cases, only a prefix of the bit sequence is needed for the
+     * path to a data object in the tree.
+     * 
    
+     * If the hash code of a data object in the set is not unique, then it is
+     * stored in a {@link HashCollisionNode}, otherwise it is stored in a
+     * {@link BitmapIndexedNode}. Since the hash codes have a fixed length,
+     * all {@link HashCollisionNode}s are located at the same, maximal depth
+     * of the tree.
+     * 
    
+     * In this implementation, a hash code has a length of
+     * {@value #HASH_CODE_LENGTH} bits, and is split up in little-endian order into parts of
+     * {@value #BIT_PARTITION_SIZE} bits (the last part contains the remaining bits).

+/**
+ * An optimized array-based binary heap with long keys.
+ * 
    
+ * This is a highly optimized implementation which uses
+ * 
      
+ * 
    1. the Wegener bottom-up heuristic and
      2. 
+ * 
    2. sentinel values
      3. 
+ * 
    
+ * The implementation uses an array
+ * in order to store the elements, providing amortized O(log(n)) time for the
+ * {@link #addAsLong} and {@link #removeAsLong} operations.
+ * Operation {@code findMin},
+ * is a worst-case O(1) operation. All bounds are worst-case if the user
+ * initializes the heap with a capacity larger or equal to the total number of
+ * elements that are going to be inserted into the heap.
+ *
+ * 
    
+ * See the following papers for details about the optimizations:

+ * 
    
+ * Note that this implementation is not synchronized. If
+ * multiple threads access a heap concurrently, and at least one of the threads
+ * modifies the heap structurally, it must be synchronized externally.
+ * (A structural modification is any operation that adds or deletes one or more
+ * elements or changing the key of some element.) This is typically accomplished
+ * by synchronizing on some object that naturally encapsulates the heap.

+/**
+ * Implements an immutable set using a Compressed Hash-Array Mapped Prefix-tree
+ * (CHAMP), with predictable iteration order.
+ * 
    
+ * Features:
+ * 
      
+ *     
    • allows null elements
      • 
+ *     
    • is immutable
      • 
+ *     
    • is thread-safe
      • 
+ *     
    • iterates in the order, in which elements were inserted
      • 
+ * 
    
+ * 
    
+ * Performance characteristics:
+ * 
      
+ *     
    • copyAdd: O(1) amortized
      • 
+ *     
    • copyRemove: O(1)
      • 
+ *     
    • contains: O(1)
      • 
+ *     
    • toMutable: O(1) + a cost distributed across subsequent updates in the mutable copy
      • 
+ *     
    • clone: O(1)
      • 
+ *     
    • iterator.next(): O(log N)
      • 
+ *     
    • getFirst(), getLast(): O(N)
      • 
+ * 
    
+ * 
    
+ * Implementation details:
+ * 
    
+ * This set performs read and write operations of single elements in O(1) time,
+ * and in O(1) space.
+ * 
    
+ * The CHAMP tree contains nodes that may be shared with other sets.
+ * 
    
+ * If a write operation is performed on a node, then this set creates a
+ * copy of the node and of all parent nodes up to the root (copy-path-on-write).
+ * Since the CHAMP tree has a fixed maximal height, the cost is O(1).
+ * 
    
+ * This set can create a mutable copy of itself in O(1) time and O(0) space
+ * using method {@link #toMutable()}}. The mutable copy shares its nodes
+ * with this set, until it has gradually replaced the nodes with exclusively
+ * owned nodes.
+ * 
    
+ * Insertion Order:
+ * 
    
+ * This set uses a counter to keep track of the insertion order.
+ * It stores the current value of the counter in the sequence number
+ * field of each data entry. If the counter wraps around, it must renumber all
+ * sequence numbers.
+ * 
    
+ * The renumbering is why the {@code add} is O(1) only in an amortized sense.
+ * 
    
+ * The iterator of the set is a priority queue, that orders the entries by
+ * their stored insertion counter value. This is why {@code iterator.next()}
+ * is O(log n).
+ *

+/**
+ * Implements a mutable set using a Compressed Hash-Array Mapped Prefix-tree
+ * (CHAMP).
+ * 
    
+ * Features:
+ * 
      
+ *     
    • allows null elements
      • 
+ *     
    • is mutable
      • 
+ *     
    • is not thread-safe
      • 
+ *     
    • does not guarantee a specific iteration order
      • 
+ * 
    
+ * 
    
+ * Performance characteristics:
+ * 
      
+ *     
    • add: O(1)
      • 
+ *     
    • remove: O(1)
      • 
+ *     
    • contains: O(1)
      • 
+ *     
    • toImmutable: O(1) + a cost distributed across subsequent updates in
+ *     this set
      • 
+ *     
    • clone: O(1) + a cost distributed across subsequent updates in this
+ *     set and in the clone
      • 
+ *     
    • iterator.next: O(log N)
      • 
+ *     
    • getFirst, getLast: O(N)
      • 
+ * 
    
+ * 
    
+ * Implementation details:
+ * 
    
+ * This set performs read and write operations of single elements in O(1) time,
+ * and in O(1) space.
+ * 
    
+ * The CHAMP tree contains nodes that may be shared with other sets, and nodes
+ * that are exclusively owned by this set.
+ * 
    
+ * If a write operation is performed on an exclusively owned node, then this
+ * set is allowed to mutate the node (mutate-on-write).
+ * If a write operation is performed on a potentially shared node, then this
+ * set is forced to create an exclusive copy of the node and of all not (yet)
+ * exclusively owned parent nodes up to the root (copy-path-on-write).
+ * Since the CHAMP tree has a fixed maximal height, the cost is O(1) in either
+ * case.
+ * 
    
+ * This set can create an immutable copy of itself in O(1) time and O(0) space
+ * using method {@link #toImmutable()}. This set loses exclusive ownership of
+ * all its tree nodes.
+ * Thus, creating an immutable copy increases the constant cost of
+ * subsequent writes, until all shared nodes have been gradually replaced by
+ * exclusively owned nodes again.
+ * 
    
+ * Note that this implementation is not synchronized.
+ * If multiple threads access this set concurrently, and at least
+ * one of the threads modifies the set, it must be synchronized
+ * externally.  This is typically accomplished by synchronizing on some
+ * object that naturally encapsulates the set.
+ *

+/**
+ * Implements an immutable map using a Compressed Hash-Array Mapped Prefix-tree
+ * (CHAMP).
+ * 
    
+ * Features:
+ * 
      
+ *     
    • allows null keys and null values
      • 
+ *     
    • is immutable
      • 
+ *     
    • is thread-safe
      • 
+ *     
    • does not guarantee a specific iteration order
      • 
+ * 
    
+ * 
    
+ * Performance characteristics:
+ * 
      
+ *     
    • copyPut: O(1)
      • 
+ *     
    • copyRemove: O(1)
      • 
+ *     
    • containsKey: O(1)
      • 
+ *     
    • toMutable: O(1) + a cost distributed across subsequent updates in the mutable copy
      • 
+ *     
    • clone: O(1)
      • 
+ *     
    • iterator.next(): O(1)
      • 
+ * 
    
+ * 
    
+ * Implementation details:
+ * 
    
+ * This map performs read and write operations of single elements in O(1) time,
+ * and in O(1) space.
+ * 
    
+ * The CHAMP tree contains nodes that may be shared with other maps.
+ * 
    
+ * If a write operation is performed on a node, then this map creates a
+ * copy of the node and of all parent nodes up to the root (copy-path-on-write).
+ * Since the CHAMP tree has a fixed maximal height, the cost is O(1).
+ * 
    
+ * This map can create a mutable copy of itself in O(1) time and O(1) space
+ * using method {@link #toMutable()}}. The mutable copy shares its nodes
+ * with this map, until it has gradually replaced the nodes with exclusively
+ * owned nodes.
+ * 
    
+ * All operations on this set can be performed concurrently, without a need for
+ * synchronisation.
+ *

+/**
+ * Implements a mutable map using a Compressed Hash-Array Mapped Prefix-tree
+ * (CHAMP).
+ * 
    
+ * Features:
+ * 
      
+ *     
    • allows null keys and null values
      • 
+ *     
    • is mutable
      • 
+ *     
    • is not thread-safe
      • 
+ *     
    • does not guarantee a specific iteration order
      • 
+ * 
    
+ * 
    
+ * Performance characteristics:
+ * 
      
+ *     
    • put: O(1)
      • 
+ *     
    • remove: O(1)
      • 
+ *     
    • containsKey: O(1)
      • 
+ *     
    • toImmutable: O(1) + a cost distributed across subsequent updates in
+ *     this map
      • 
+ *     
    • clone: O(1) + a cost distributed across subsequent updates in this
+ *     map and in the clone
      • 
+ *     
    • iterator.next: O(1)
      • 
+ * 
    
+ * 
    
+ * Implementation details:
+ * 
    
+ * This map performs read and write operations of single elements in O(1) time,
+ * and in O(1) space.
+ * 
    
+ * The CHAMP tree contains nodes that may be shared with other maps, and nodes
+ * that are exclusively owned by this map.
+ * 
    
+ * If a write operation is performed on an exclusively owned node, then this
+ * map is allowed to mutate the node (mutate-on-write).
+ * If a write operation is performed on a potentially shared node, then this
+ * map is forced to create an exclusive copy of the node and of all not (yet)
+ * exclusively owned parent nodes up to the root (copy-path-on-write).
+ * Since the CHAMP tree has a fixed maximal height, the cost is O(1) in either
+ * case.
+ * 
    
+ * This map can create an immutable copy of itself in O(1) time and O(1) space
+ * using method {@link #toImmutable()}. This map loses exclusive ownership of
+ * all its tree nodes.
+ * Thus, creating an immutable copy increases the constant cost of
+ * subsequent writes, until all shared nodes have been gradually replaced by
+ * exclusively owned nodes again.
+ *

+/**
+ * Implements an immutable map using a Compressed Hash-Array Mapped Prefix-tree
+ * (CHAMP), with predictable iteration order.
+ * 
    
+ * Features:
+ * 
      
+ *     
    • allows null keys and null values
      • 
+ *     
    • is immutable
      • 
+ *     
    • is thread-safe
      • 
+ *     
    • iterates in the order, in which keys were inserted
      • 
+ * 
    
+ * 
    
+ * Performance characteristics:
+ * 
      
+ *     
    • copyPut, copyPutFirst, copyPutLast: O(1) amortized due to
+ *     renumbering
      • 
+ *     
    • copyRemove: O(1) amortized due to renumbering
      • 
+ *     
    • containsKey: O(1)
      • 
+ *     
    • toMutable: O(1) + a cost distributed across subsequent updates in
+ *     the mutable copy
      • 
+ *     
    • clone: O(1)
      • 
+ *     
    • iterator creation: O(N)
      • 
+ *     
    • iterator.next: O(1) with bucket sort or O(log N) with a heap
      • 
+ *     
    • getFirst, getLast: O(N)
      • 
+ * 
    
+ * 
    
+ * Implementation details:
+ * 
    
+ * This map performs read and write operations of single elements in O(1) time,
+ * and in O(1) space.
+ * 
    
+ * The CHAMP tree contains nodes that may be shared with other maps.
+ * 
    
+ * If a write operation is performed on a node, then this map creates a
+ * copy of the node and of all parent nodes up to the root (copy-path-on-write).
+ * Since the CHAMP tree has a fixed maximal height, the cost is O(1).
+ * 
    
+ * This map can create a mutable copy of itself in O(1) time and O(1) space
+ * using method {@link #toMutable()}}. The mutable copy shares its nodes
+ * with this map, until it has gradually replaced the nodes with exclusively
+ * owned nodes.
+ * 
    
+ * All operations on this set can be performed concurrently, without a need for
+ * synchronisation.
+ * 
    
+ * Insertion Order:
+ * 
    
+ * This map uses a counter to keep track of the insertion order.
+ * It stores the current value of the counter in the sequence number
+ * field of each data entry. If the counter wraps around, it must renumber all
+ * sequence numbers.
+ * 
    
+ * The renumbering is why the {@code copyPut} is O(1) only in an amortized sense.
+ * 
    
+ * The iterator of the map is a priority queue, that orders the entries by
+ * their stored insertion counter value. This is why {@code iterator.next()}
+ * is O(log n).
+ *

+/**
+ * Implements a mutable map using a Compressed Hash-Array Mapped Prefix-tree
+ * (CHAMP), with predictable iteration order.
+ * 
    
+ * Features:
+ * 
      
+ *     
    • allows null keys and null values
      • 
+ *     
    • is mutable
      • 
+ *     
    • is not thread-safe
      • 
+ *     
    • iterates in the order, in which keys were inserted
      • 
+ * 
    
+ * 
    
+ * Performance characteristics:
+ * 
      
+ *     
    • put, putFirst, putLast: O(1) amortized due to renumbering
      • 
+ *     
    • remove: O(1)
      • 
+ *     
    • containsKey: O(1)
      • 
+ *     
    • toImmutable: O(1) + a cost distributed across subsequent updates in
+ *     this mutable map
      • 
+ *     
    • clone: O(1) + a cost distributed across subsequent updates in this
+ *     mutable map and in the clone
      • 
+ *     
    • iterator creation: O(N)
      • 
+ *     
    • iterator.next: O(1) with bucket sort or O(log N) with a heap
      • 
+ *     
    • getFirst, getLast: O(N)
      • 
+ * 
    
+ * 
    
+ * Implementation details:
+ * 
    
+ * This map performs read and write operations of single elements in O(1) time,
+ * and in O(1) space.
+ * 
    
+ * The CHAMP tree contains nodes that may be shared with other maps, and nodes
+ * that are exclusively owned by this map.
+ * 
    
+ * If a write operation is performed on an exclusively owned node, then this
+ * map is allowed to mutate the node (mutate-on-write).
+ * If a write operation is performed on a potentially shared node, then this
+ * map is forced to create an exclusive copy of the node and of all not (yet)
+ * exclusively owned parent nodes up to the root (copy-path-on-write).
+ * Since the CHAMP tree has a fixed maximal height, the cost is O(1) in either
+ * case.
+ * 
    
+ * This map can create an immutable copy of itself in O(1) time and O(1) space
+ * using method {@link #toImmutable()}. This map loses exclusive ownership of
+ * all its tree nodes.
+ * Thus, creating an immutable copy increases the constant cost of
+ * subsequent writes, until all shared nodes have been gradually replaced by
+ * exclusively owned nodes again.
+ * 
    
+ * Insertion Order:
+ * 
    
+ * This map uses a counter to keep track of the insertion order.
+ * It stores the current value of the counter in the sequence number
+ * field of each data entry. If the counter wraps around, it must renumber all
+ * sequence numbers.
+ * 
    
+ * The renumbering is why the {@code copyPut} is O(1) only in an amortized sense.
+ * 
    
+ * The iterator of the map is a priority queue, that orders the entries by
+ * their stored insertion counter value. This is why {@code iterator.next()}
+ * is O(log n).

+ * Insertion Order:

+ * This set uses a counter to keep track of the insertion order.
+ * It stores the current value of the counter in the sequence number

+ * The renumbering is why the {@code add} is O(1) only in an amortized sense.

- * Represents a node in a CHAMP trie.
+ * Represents a node in a 'Compressed Hash-Array Mapped Prefix-tree'
+ * (CHAMP) trie.
+ * 
    
+ * A trie is a tree structure that stores a set of data objects; the
+ * path to a data object is determined by a bit sequence derived from the data
+ * object.
+ * 
    
+ * In a CHAMP trie, the bit sequence is derived from the hash code of a data
+ * object. A hash code is a bit sequence with a fixed length. This bit sequence
+ * is split up into parts. Each part is used as the index to the next child node
+ * in the tree, starting from the root node of the tree.
+ * 
    
+ * The nodes of a CHAMP trie are compressed. Instead of allocating a node for
+ * each data object, the data objects are stored directly in the ancestor node
+ * at which the path to the data object starts to become unique. This means,

+/**
+ * Implements an immutable set using a Compressed Hash-Array Mapped Prefix-tree
+ * (CHAMP), with predictable iteration order.
+ * 
    
+ * Features:
+ * 
      
+ *     
    • supports up to 230 elements
      • 
+ *     
    • allows null elements
      • 
+ *     
    • is immutable
      • 
+ *     
    • is thread-safe
      • 
+ *     
    • iterates in the order, in which elements were inserted
      • 
+ * 
    
+ * 
    
+ * Performance characteristics:
+ * 
      
+ *     
    • copyAdd: O(1) amortized
      • 
+ *     
    • copyRemove: O(1)
      • 
+ *     
    • contains: O(1)
      • 
+ *     
    • toMutable: O(1) + O(log N) distributed across subsequent updates in the mutable copy
      • 
+ *     
    • clone: O(1)
      • 
+ *     
    • iterator creation: O(N)
      • 
+ *     
    • iterator.next: O(1) with bucket sort, O(log N) with heap sort
      • 
+ *     
    • getFirst(), getLast(): O(N)
      • 
+ * 
    
+ * 
    
+ * Implementation details:
+ * 
    
+ * This set performs read and write operations of single elements in O(1) time,
+ * and in O(1) space.
+ * 
    
+ * The CHAMP tree contains nodes that may be shared with other sets.
+ * 
    
+ * If a write operation is performed on a node, then this set creates a
+ * copy of the node and of all parent nodes up to the root (copy-path-on-write).
+ * Since the CHAMP tree has a fixed maximal height, the cost is O(1).
+ * 
    
+ * This set can create a mutable copy of itself in O(1) time and O(1) space
+ * using method {@link #toMutable()}}. The mutable copy shares its nodes
+ * with this set, until it has gradually replaced the nodes with exclusively
+ * owned nodes.
+ * 
    
+ * Insertion Order:
+ * 
    
+ * This set uses a counter to keep track of the insertion order.
+ * It stores the current value of the counter in the sequence number
+ * field of each data entry. If the counter wraps around, it must renumber all
+ * sequence numbers.
+ * 
    
+ * The renumbering is why the {@code add} is O(1) only in an amortized sense.
+ * 
    
+ * The iterator of the set is a priority queue, that orders the entries by
+ * their stored insertion counter value. This is why {@code iterator.next()}
+ * is O(log n).
+ *

+/**
+ * Implements a mutable set using a Compressed Hash-Array Mapped Prefix-tree
+ * (CHAMP), with predictable iteration order.
+ * 
    
+ * Features:
+ * 
      
+ *     
    • supports up to 230 elements
      • 
+ *     
    • allows null elements
      • 
+ *     
    • is mutable
      • 
+ *     
    • is not thread-safe
      • 
+ *     
    • iterates in the order, in which elements were inserted
      • 
+ * 
    
+ * 
    
+ * Performance characteristics:
+ * 
      
+ *     
    • add: O(1) amortized
      • 
+ *     
    • remove: O(1)
      • 
+ *     
    • contains: O(1)
      • 
+ *     
    • toImmutable: O(1) + O(log N) distributed across subsequent updates in
+ *     this set
      • 
+ *     
    • clone: O(1) + O(log N) distributed across subsequent updates in this
+ *     set and in the clone
      • 
+ *     
    • iterator creation: O(N)
      • 
+ *     
    • iterator.next: O(1) with bucket sort, O(log N) with heap sort
      • 
+ *     
    • getFirst, getLast: O(N)
      • 
+ * 
    
+ * 
    
+ * Implementation details:
+ * 
    
+ * This set performs read and write operations of single elements in O(1) time,
+ * and in O(1) space.
+ * 
    
+ * The CHAMP trie contains nodes that may be shared with other sets, and nodes
+ * that are exclusively owned by this set.
+ * 
    
+ * If a write operation is performed on an exclusively owned node, then this
+ * set is allowed to mutate the node (mutate-on-write).
+ * If a write operation is performed on a potentially shared node, then this
+ * set is forced to create an exclusive copy of the node and of all not (yet)
+ * exclusively owned parent nodes up to the root (copy-path-on-write).
+ * Since the CHAMP trie has a fixed maximal height, the cost is O(1) in either
+ * case.
+ * 
    
+ * This set can create an immutable copy of itself in O(1) time and O(1) space
+ * using method {@link #toImmutable()}. This set loses exclusive ownership of
+ * all its tree nodes.
+ * Thus, creating an immutable copy increases the constant cost of
+ * subsequent writes, until all shared nodes have been gradually replaced by
+ * exclusively owned nodes again.
+ * 
    
+ * Insertion Order:
+ * 
    
+ * This set uses a counter to keep track of the insertion order.
+ * It stores the current value of the counter in the sequence number
+ * field of each data entry. If the counter wraps around, it must renumber all
+ * sequence numbers.
+ * 
    
+ * The renumbering is why the {@code add} is O(1) only in an amortized sense.
+ * 
    
+ * The iterator of the set is a priority queue, that orders the entries by
+ * their stored insertion counter value. This is why {@code iterator.next()}
+ * is O(log n).
+ * 
    
+ * Note that this implementation is not synchronized.
+ * If multiple threads access this set concurrently, and at least
+ * one of the threads modifies the set, it must be synchronized
+ * externally.  This is typically accomplished by synchronizing on some
+ * object that naturally encapsulates the set.
+ *

+/**
+ * Implements an immutable map using two Compressed Hash-Array Mapped Prefix-trees
+ * (CHAMP), with predictable iteration order.
+ * 
    
+ * Features:
+ * 
      
+ *     
    • supports up to 230 entries
      • 
+ *     
    • allows null keys and null values
      • 
+ *     
    • is immutable
      • 
+ *     
    • is thread-safe
      • 
+ *     
    • iterates in the order, in which keys were inserted
      • 
+ * 
    
+ * 
    
+ * Performance characteristics:
+ * 
      
+ *     
    • copyPut, copyPutFirst, copyPutLast: O(1) amortized, due to
+ *     renumbering
      • 
+ *     
    • copyRemove: O(1) amortized, due to renumbering
      • 
+ *     
    • containsKey: O(1)
      • 
+ *     
    • toMutable: O(1) + O(log N) distributed across subsequent updates in
+ *     the mutable copy
      • 
+ *     
    • clone: O(1)
      • 
+ *     
    • iterator creation: O(1)
      • 
+ *     
    • iterator.next: O(1) with bucket sort, O(log N) with heap sort
      • 
+ *     
    • getFirst, getLast: O(1)
      • 
+ * 
    
+ * 
    
+ * Implementation details:
+ * 
    
+ * This map performs read and write operations of single elements in O(1) time,
+ * and in O(1) space.
+ * 
    
+ * The CHAMP trie contains nodes that may be shared with other maps.
+ * 
    
+ * If a write operation is performed on a node, then this map creates a
+ * copy of the node and of all parent nodes up to the root (copy-path-on-write).
+ * Since the CHAMP trie has a fixed maximal height, the cost is O(1).
+ * 
    
+ * This map can create a mutable copy of itself in O(1) time and O(1) space
+ * using method {@link #toMutable()}}. The mutable copy shares its nodes
+ * with this map, until it has gradually replaced the nodes with exclusively
+ * owned nodes.
+ * 
    
+ * All operations on this set can be performed concurrently, without a need for
+ * synchronisation.
+ * 
    
+ * Insertion Order:
+ * 
    
+ * This map uses a counter to keep track of the insertion order.
+ * It stores the current value of the counter in the sequence number
+ * field of each data entry. If the counter wraps around, it must renumber all
+ * sequence numbers.
+ * 
    
+ * The renumbering is why the {@code put} and {@code remove} methods are
+ * O(1) only in an amortized sense.
+ * 
    
+ * 
    
+ * To support iteration, a second CHAMP trie is maintained. The second CHAMP
+ * trie has the same contents as the first. However, we use the sequence number
+ * for computing the hash code of an element.
+ * 
    
+ * In this implementation, a hash code has a length of
+ * 32 bits, and is split up in little-endian order into 7 parts of
+ * 5 bits (the last part contains the remaining bits).
+ * 
    
+ * We convert the sequence number to unsigned 32 by adding Integer.MIN_VALUE
+ * to it. And then we reorder its bits from
+ * 66666555554444433333222221111100 to 00111112222233333444445555566666.

+/**
+ * Implements a mutable map using two Compressed Hash-Array Mapped Prefix-trees
+ * (CHAMP), with predictable iteration order.
+ * 
    
+ * Features:
+ * 
      
+ *     
    • supports up to 230 entries
      • 
+ *     
    • allows null keys and null values
      • 
+ *     
    • is mutable
      • 
+ *     
    • is not thread-safe
      • 
+ *     
    • iterates in the order, in which keys were inserted
      • 
+ * 
    
+ * 
    
+ * Performance characteristics:
+ * 
      
+ *     
    • put, putFirst, putLast: O(1) amortized, due to renumbering
      • 
+ *     
    • remove: O(1) amortized, due to renumbering
      • 
+ *     
    • containsKey: O(1)
      • 
+ *     
    • toImmutable: O(1) + O(log N) distributed across subsequent updates in
+ *     this mutable map
      • 
+ *     
    • clone: O(1) + O(log N) distributed across subsequent updates in this
+ *     mutable map and in the clone
      • 
+ *     
    • iterator creation: O(1)
      • 
+ *     
    • iterator.next: O(1) with bucket sort, O(log N) with heap sort
      • 
+ *     
    • getFirst, getLast: O(1)
      • 
+ * 
    
+ * 
    
+ * Implementation details:
+ * 
    
+ * This map performs read and write operations of single elements in O(1) time,
+ * and in O(1) space.
+ * 
    
+ * The CHAMP trie contains nodes that may be shared with other maps, and nodes
+ * that are exclusively owned by this map.
+ * 
    
+ * If a write operation is performed on an exclusively owned node, then this
+ * map is allowed to mutate the node (mutate-on-write).
+ * If a write operation is performed on a potentially shared node, then this
+ * map is forced to create an exclusive copy of the node and of all not (yet)
+ * exclusively owned parent nodes up to the root (copy-path-on-write).
+ * Since the CHAMP trie has a fixed maximal height, the cost is O(1) in either
+ * case.
+ * 
    
+ * This map can create an immutable copy of itself in O(1) time and O(1) space
+ * using method {@link #toImmutable()}. This map loses exclusive ownership of
+ * all its tree nodes.
+ * Thus, creating an immutable copy increases the constant cost of
+ * subsequent writes, until all shared nodes have been gradually replaced by
+ * exclusively owned nodes again.
+ * 
    
+ * Insertion Order:
+ * 
    
+ * This map uses a counter to keep track of the insertion order.
+ * It stores the current value of the counter in the sequence number
+ * field of each data entry. If the counter wraps around, it must renumber all
+ * sequence numbers.
+ * 
    
+ * The renumbering is why the {@code put} and {@code remove} methods are
+ * O(1) only in an amortized sense.
+ * 
    
+ * To support iteration, a second CHAMP trie is maintained. The second CHAMP
+ * trie has the same contents as the first. However, we use the sequence number
+ * for computing the hash code of an element.
+ * 
    
+ * In this implementation, a hash code has a length of
+ * 32 bits, and is split up in little-endian order into 7 parts of
+ * 5 bits (the last part contains the remaining bits).
+ * 
    
+ * We convert the sequence number to unsigned 32 by adding Integer.MIN_VALUE
+ * to it. And then we reorder its bits from
+ * 66666555554444433333222221111100 to 00111112222233333444445555566666.

-/**
- * Implements an immutable map using a Compressed Hash-Array Mapped Prefix-tree
- * (CHAMP), with predictable iteration order.
- * 
    
- * Features:
- * 
      
- *     
    • supports up to 230 entries
      • 
- *     
    • allows null keys and null values
      • 
- *     
    • is immutable
      • 
- *     
    • is thread-safe
      • 
- *     
    • iterates in the order, in which keys were inserted
      • 
- * 
    
- * 
    
- * Performance characteristics:
- * 
      
- *     
    • copyPut, copyPutFirst, copyPutLast: O(1) amortized due to
- *     renumbering
      • 
- *     
    • copyRemove: O(1) amortized due to renumbering
      • 
- *     
    • containsKey: O(1)
      • 
- *     
    • toMutable: O(1) + O(log N) distributed across subsequent updates in
- *     the mutable copy
      • 
- *     
    • clone: O(1)
      • 
- *     
    • iterator creation: O(N)
      • 
- *     
    • iterator.next: O(1) with bucket sort, O(log N) with heap sort
      • 
- *     
    • getFirst, getLast: O(N)
      • 
- * 
    
- * 
    
- * Implementation details:
- * 
    
- * This map performs read and write operations of single elements in O(1) time,
- * and in O(1) space.
- * 
    
- * The CHAMP tree contains nodes that may be shared with other maps.
- * 
    
- * If a write operation is performed on a node, then this map creates a
- * copy of the node and of all parent nodes up to the root (copy-path-on-write).
- * Since the CHAMP tree has a fixed maximal height, the cost is O(1).
- * 
    
- * This map can create a mutable copy of itself in O(1) time and O(1) space
- * using method {@link #toMutable()}}. The mutable copy shares its nodes
- * with this map, until it has gradually replaced the nodes with exclusively
- * owned nodes.
- * 
    
- * All operations on this set can be performed concurrently, without a need for
- * synchronisation.
- * 
    
- * Insertion Order:
- * 
    
- * This map uses a counter to keep track of the insertion order.
- * It stores the current value of the counter in the sequence number
- * field of each data entry. If the counter wraps around, it must renumber all
- * sequence numbers.
- * 
    
- * The renumbering is why the {@code copyPut} is O(1) only in an amortized sense.
- * 
    
- * The iterator of the map is a priority queue, that orders the entries by
- * their stored insertion counter value. This is why {@code iterator.next()}
- * is O(log n).

-/**
- * Implements an immutable set using a Compressed Hash-Array Mapped Prefix-tree
- * (CHAMP), with predictable iteration order.
- * 
    
- * Features:
- * 
      
- *     
    • supports up to 230 elements
      • 
- *     
    • allows null elements
      • 
- *     
    • is immutable
      • 
- *     
    • is thread-safe
      • 
- *     
    • iterates in the order, in which elements were inserted
      • 
- * 
    
- * 
    
- * Performance characteristics:
- * 
      
- *     
    • copyAdd: O(1) amortized
      • 
- *     
    • copyRemove: O(1)
      • 
- *     
    • contains: O(1)
      • 
- *     
    • toMutable: O(1) + O(log N) distributed across subsequent updates in the mutable copy
      • 
- *     
    • clone: O(1)
      • 
- *     
    • iterator creation: O(N)
      • 
- *     
    • iterator.next: O(1) with bucket sort, O(log N) with heap sort
      • 
- *     
    • getFirst(), getLast(): O(N)
      • 
- * 
    
- * 
    
- * Implementation details:
- * 
    
- * This set performs read and write operations of single elements in O(1) time,
- * and in O(1) space.
- * 
    
- * The CHAMP tree contains nodes that may be shared with other sets.
- * 
    
- * If a write operation is performed on a node, then this set creates a
- * copy of the node and of all parent nodes up to the root (copy-path-on-write).
- * Since the CHAMP tree has a fixed maximal height, the cost is O(1).
- * 
    
- * This set can create a mutable copy of itself in O(1) time and O(1) space
- * using method {@link #toMutable()}}. The mutable copy shares its nodes
- * with this set, until it has gradually replaced the nodes with exclusively
- * owned nodes.
- * 
    
- * Insertion Order:
- * 
    
- * This set uses a counter to keep track of the insertion order.
- * It stores the current value of the counter in the sequence number
- * field of each data entry. If the counter wraps around, it must renumber all
- * sequence numbers.
- * 
    
- * The renumbering is why the {@code add} is O(1) only in an amortized sense.
- * 
    
- * The iterator of the set is a priority queue, that orders the entries by
- * their stored insertion counter value. This is why {@code iterator.next()}
- * is O(log n).
- *

-/**
- * An optimized array-based binary heap with long keys.
- * 
    
- * This is a highly optimized implementation which uses
- * 
      
- * 
    1. the Wegener bottom-up heuristic and
      2. 
- * 
    2. sentinel values
      3. 
- * 
    
- * The implementation uses an array
- * in order to store the elements, providing amortized O(log(n)) time for the
- * {@link #addAsLong} and {@link #removeAsLong} operations.
- * Operation {@code findMin},
- * is a worst-case O(1) operation. All bounds are worst-case if the user
- * initializes the heap with a capacity larger or equal to the total number of
- * elements that are going to be inserted into the heap.
- *
- * 
    
- * See the following papers for details about the optimizations:

- * an average, QUICKSORT (if n is not very small). Theoretical Computer Science,
- * 118(1), 81--98, 1993.

- *
- * 
    
- * Note that this implementation is not synchronized. If
- * multiple threads access a heap concurrently, and at least one of the threads
- * modifies the heap structurally, it must be synchronized externally.
- * (A structural modification is any operation that adds or deletes one or more
- * elements or changing the key of some element.) This is typically accomplished
- * by synchronizing on some object that naturally encapsulates the heap.

-/**
- * Implements a mutable map using a Compressed Hash-Array Mapped Prefix-tree
- * (CHAMP), with predictable iteration order.
- * 
    
- * Features:
- * 
      
- *     
    • supports up to 230 entries
      • 
- *     
    • allows null keys and null values
      • 
- *     
    • is mutable
      • 
- *     
    • is not thread-safe
      • 
- *     
    • iterates in the order, in which keys were inserted
      • 
- * 
    
- * 
    
- * Performance characteristics:
- * 
      
- *     
    • put, putFirst, putLast: O(1) amortized due to renumbering
      • 
- *     
    • remove: O(1)
      • 
- *     
    • containsKey: O(1)
      • 
- *     
    • toImmutable: O(1) + O(log N) distributed across subsequent updates in
- *     this mutable map
      • 
- *     
    • clone: O(1) + O(log N) distributed across subsequent updates in this
- *     mutable map and in the clone
      • 
- *     
    • iterator creation: O(N)
      • 
- *     
    • iterator.next: O(1) with bucket sort, O(log N) with heap sort
      • 
- *     
    • getFirst, getLast: O(N)
      • 
- * 
    
- * 
    
- * Implementation details:
- * 
    
- * This map performs read and write operations of single elements in O(1) time,
- * and in O(1) space.
- * 
    
- * The CHAMP tree contains nodes that may be shared with other maps, and nodes
- * that are exclusively owned by this map.
- * 
    
- * If a write operation is performed on an exclusively owned node, then this
- * map is allowed to mutate the node (mutate-on-write).
- * If a write operation is performed on a potentially shared node, then this
- * map is forced to create an exclusive copy of the node and of all not (yet)
- * exclusively owned parent nodes up to the root (copy-path-on-write).
- * Since the CHAMP tree has a fixed maximal height, the cost is O(1) in either
- * case.
- * 
    
- * This map can create an immutable copy of itself in O(1) time and O(1) space
- * using method {@link #toImmutable()}. This map loses exclusive ownership of
- * all its tree nodes.
- * Thus, creating an immutable copy increases the constant cost of
- * subsequent writes, until all shared nodes have been gradually replaced by
- * exclusively owned nodes again.
- * 
    
- * Insertion Order:
- * 
    
- * This map uses a counter to keep track of the insertion order.
- * It stores the current value of the counter in the sequence number
- * field of each data entry. If the counter wraps around, it must renumber all
- * sequence numbers.
- * 
    
- * The renumbering is why the {@code copyPut} is O(1) only in an amortized sense.
- * 
    
- * The iterator of the map is a priority queue, that orders the entries by
- * their stored insertion counter value. This is why {@code iterator.next()}
- * is O(log n).

-/**
- * Implements a mutable set using a Compressed Hash-Array Mapped Prefix-tree
- * (CHAMP), with predictable iteration order.
- * 
    
- * Features:
- * 
      
- *     
    • supports up to 230 elements
      • 
- *     
    • allows null elements
      • 
- *     
    • is mutable
      • 
- *     
    • is not thread-safe
      • 
- *     
    • iterates in the order, in which elements were inserted
      • 
- * 
    
- * 
    
- * Performance characteristics:
- * 
      
- *     
    • add: O(1) amortized
      • 
- *     
    • remove: O(1)
      • 
- *     
    • contains: O(1)
      • 
- *     
    • toImmutable: O(1) + O(log N) distributed across subsequent updates in
- *     this set
      • 
- *     
    • clone: O(1) + O(log N) distributed across subsequent updates in this
- *     set and in the clone
      • 
- *     
    • iterator creation: O(N)
      • 
- *     
    • iterator.next: O(1) with bucket sort, O(log N) with heap sort
      • 
- *     
    • getFirst, getLast: O(N)
      • 
- * 
    
- * 
    
- * Implementation details:
- * 
    
- * This set performs read and write operations of single elements in O(1) time,
- * and in O(1) space.
- * 
    
- * The CHAMP tree contains nodes that may be shared with other sets, and nodes
- * that are exclusively owned by this set.
- * 
    
- * If a write operation is performed on an exclusively owned node, then this
- * set is allowed to mutate the node (mutate-on-write).
- * If a write operation is performed on a potentially shared node, then this
- * set is forced to create an exclusive copy of the node and of all not (yet)
- * exclusively owned parent nodes up to the root (copy-path-on-write).
- * Since the CHAMP tree has a fixed maximal height, the cost is O(1) in either
- * case.
- * 
    
- * This set can create an immutable copy of itself in O(1) time and O(1) space
- * using method {@link #toImmutable()}. This set loses exclusive ownership of
- * all its tree nodes.
- * Thus, creating an immutable copy increases the constant cost of
- * subsequent writes, until all shared nodes have been gradually replaced by
- * exclusively owned nodes again.
- * 
    
- * Insertion Order:
- * 
    
- * This set uses a counter to keep track of the insertion order.
- * It stores the current value of the counter in the sequence number
- * field of each data entry. If the counter wraps around, it must renumber all
- * sequence numbers.
- * 
    
- * The renumbering is why the {@code add} is O(1) only in an amortized sense.
- * 
    
- * The iterator of the set is a priority queue, that orders the entries by
- * their stored insertion counter value. This is why {@code iterator.next()}
- * is O(log n).
- * 
    
- * Note that this implementation is not synchronized.
- * If multiple threads access this set concurrently, and at least
- * one of the threads modifies the set, it must be synchronized
- * externally.  This is typically accomplished by synchronizing on some
- * object that naturally encapsulates the set.

Subject: [PATCH 122/169] Rename champ collection classes to HashMap,
 LinkedHashMap and so on. Lump all utility classes into a single class,
 because Java 8 does not support the notion of non-exported packages.

+     * 
    
+     * A trie is a tree structure that stores a set of data objects; the
+     * path to a data object is determined by a bit sequence derived from the data
+     * object.
+     * 
    
+     * In a CHAMP trie, the bit sequence is derived from the hash code of a data
+     * object. A hash code is a bit sequence with a fixed length. This bit sequence
+     * is split up into parts. Each part is used as the index to the next child node
+     * in the tree, starting from the root node of the tree.
+     * 
    
+     * The nodes of a CHAMP trie are compressed. Instead of allocating a node for
+     * each data object, the data objects are stored directly in the ancestor node
+     * at which the path to the data object starts to become unique. This means,
+     * that in most cases, only a prefix of the bit sequence is needed for the
+     * path to a data object in the tree.
+     * 
    
+     * If the hash code of a data object in the set is not unique, then it is
+     * stored in a {@link HashCollisionNode}, otherwise it is stored in a
+     * {@link BitmapIndexedNode}. Since the hash codes have a fixed length,
+     * all {@link HashCollisionNode}s are located at the same, maximal depth
+     * of the tree.
+     * 
    
+     * In this implementation, a hash code has a length of
+     * {@value #HASH_CODE_LENGTH} bits, and is split up in little-endian order into parts of
+     * {@value #BIT_PARTITION_SIZE} bits (the last part contains the remaining bits).

-/**
- * Represents a node in a 'Compressed Hash-Array Mapped Prefix-tree'
- * (CHAMP) trie.
- * 
    
- * A trie is a tree structure that stores a set of data objects; the
- * path to a data object is determined by a bit sequence derived from the data
- * object.
- * 
    
- * In a CHAMP trie, the bit sequence is derived from the hash code of a data
- * object. A hash code is a bit sequence with a fixed length. This bit sequence
- * is split up into parts. Each part is used as the index to the next child node
- * in the tree, starting from the root node of the tree.
- * 
    
- * The nodes of a CHAMP trie are compressed. Instead of allocating a node for
- * each data object, the data objects are stored directly in the ancestor node
- * at which the path to the data object starts to become unique. This means,
- * that in most cases, only a prefix of the bit sequence is needed for the
- * path to a data object in the tree.
- * 
    
- * If the hash code of a data object in the set is not unique, then it is
- * stored in a {@link HashCollisionNode}, otherwise it is stored in a
- * {@link BitmapIndexedNode}. Since the hash codes have a fixed length,
- * all {@link HashCollisionNode}s are located at the same, maximal depth
- * of the tree.
- * 
    
- * In this implementation, a hash code has a length of
- * {@value #HASH_CODE_LENGTH} bits, and is split up in little-endian order into parts of
- * {@value #BIT_PARTITION_SIZE} bits (the last part contains the remaining bits).
- *
- * @param  the type of the data objects that are stored in this trie

 /**
- * An immutable {@code HashMap} implementation based on a
- * Hash array mapped trie (HAMT).
+ * Implements an immutable map using a Compressed Hash-Array Mapped Prefix-tree
+ * (CHAMP).
+ * 
    
+ * Features:
+ * 
      
+ *     
    • supports up to 230 entries
      • 
+ *     
    • allows null keys and null values
      • 
+ *     
    • is immutable
      • 
+ *     
    • is thread-safe
      • 
+ *     
    • does not guarantee a specific iteration order
      • 
+ * 
    
+ * 
    
+ * Performance characteristics:
+ * 
      
+ *     
    • copyPut: O(1)
      • 
+ *     
    • copyRemove: O(1)
      • 
+ *     
    • containsKey: O(1)
      • 
+ *     
    • toMutable: O(1) + O(log N) distributed across subsequent updates in the mutable copy
      • 
+ *     
    • clone: O(1)
      • 
+ *     
    • iterator.next(): O(1)
      • 
+ * 
    
+ * 
    
+ * Implementation details:
+ * 
    
+ * This map performs read and write operations of single elements in O(1) time,
+ * and in O(1) space.
+ * 
    
+ * The CHAMP tree contains nodes that may be shared with other maps.
+ * 
    
+ * If a write operation is performed on a node, then this map creates a
+ * copy of the node and of all parent nodes up to the root (copy-path-on-write).
+ * Since the CHAMP tree has a fixed maximal height, the cost is O(1).
+ * 
    
+ * This map can create a mutable copy of itself in O(1) time and O(1) space
+ * using method {@link #toMutable()}}. The mutable copy shares its nodes
+ * with this map, until it has gradually replaced the nodes with exclusively
+ * owned nodes.
+ * 
    
+ * All operations on this set can be performed concurrently, without a need for
+ * synchronisation.
+ *

 /**
- * An immutable {@code HashSet} implementation.
+ * Implements an immutable set using a Compressed Hash-Array Mapped Prefix-tree
+ * (CHAMP).
+ * 
    
+ * Features:
+ * 
      
+ *     
    • supports up to 230 elements
      • 
+ *     
    • allows null elements
      • 
+ *     
    • is immutable
      • 
+ *     
    • is thread-safe
      • 
+ *     
    • does not guarantee a specific iteration order
      • 
+ * 
    
+ * 
    
+ * Performance characteristics:
+ * 
      
+ *     
    • add: O(1)
      • 
+ *     
    • remove: O(1)
      • 
+ *     
    • contains: O(1)
      • 
+ *     
    • toMutable: O(1) + O(log N) distributed across subsequent updates in the mutable copy
      • 
+ *     
    • clone: O(1)
      • 
+ *     
    • iterator.next(): O(1)
      • 
+ * 
    
+ * 
    
+ * Implementation details:
+ * 
    
+ * This set performs read and write operations of single elements in O(1) time,
+ * and in O(1) space.
+ * 
    
+ * The CHAMP tree contains nodes that may be shared with other sets.
+ * 
    
+ * If a write operation is performed on a node, then this set creates a
+ * copy of the node and of all parent nodes up to the root (copy-path-on-write).
+ * Since the CHAMP tree has a fixed maximal height, the cost is O(1).
+ * 
    
+ * This set can create a mutable copy of itself in O(1) time and O(1) space
+ * using method {@code #toMutable()}}. The mutable copy shares its nodes
+ * with this set, until it has gradually replaced the nodes with exclusively
+ * owned nodes.

 /**
- * An immutable {@code LinkedHashMap} implementation that has predictable (insertion-order) iteration.
+ * Implements an immutable map using two Compressed Hash-Array Mapped Prefix-trees
+ * (CHAMP), with predictable iteration order.
+ * 
    
+ * Features:
+ * 
      
+ *     
    • supports up to 230 entries
      • 
+ *     
    • allows null keys and null values
      • 
+ *     
    • is immutable
      • 
+ *     
    • is thread-safe
      • 
+ *     
    • iterates in the order, in which keys were inserted
      • 
+ * 
    
+ * 
    
+ * Performance characteristics:
+ * 
      
+ *     
    • copyPut, copyPutFirst, copyPutLast: O(1) amortized, due to
+ *     renumbering
      • 
+ *     
    • copyRemove: O(1) amortized, due to renumbering
      • 
+ *     
    • containsKey: O(1)
      • 
+ *     
    • toMutable: O(1) + O(log N) distributed across subsequent updates in
+ *     the mutable copy
      • 
+ *     
    • clone: O(1)
      • 
+ *     
    • iterator creation: O(1)
      • 
+ *     
    • iterator.next: O(1) with bucket sort, O(log N) with heap sort
      • 
+ *     
    • getFirst, getLast: O(1)
      • 
+ * 
    
+ * 
    
+ * Implementation details:
+ * 
    
+ * This map performs read and write operations of single elements in O(1) time,
+ * and in O(1) space.
+ * 
    
+ * The CHAMP trie contains nodes that may be shared with other maps.
+ * 
    
+ * If a write operation is performed on a node, then this map creates a
+ * copy of the node and of all parent nodes up to the root (copy-path-on-write).
+ * Since the CHAMP trie has a fixed maximal height, the cost is O(1).
+ * 
    
+ * This map can create a mutable copy of itself in O(1) time and O(1) space
+ * using method {@link #toMutable()}}. The mutable copy shares its nodes
+ * with this map, until it has gradually replaced the nodes with exclusively
+ * owned nodes.
+ * 
    
+ * All operations on this set can be performed concurrently, without a need for
+ * synchronisation.
+ * 
    
+ * Insertion Order:
+ * 
    
+ * This map uses a counter to keep track of the insertion order.
+ * It stores the current value of the counter in the sequence number
+ * field of each data entry. If the counter wraps around, it must renumber all
+ * sequence numbers.
+ * 
    
+ * The renumbering is why the {@code put} and {@code remove} methods are
+ * O(1) only in an amortized sense.
+ * 
    
+ * To support iteration, a second CHAMP trie is maintained. The second CHAMP
+ * trie has the same contents as the first. However, we use the sequence number
+ * for computing the hash code of an element.
+ * 
    
+ * In this implementation, a hash code has a length of
+ * 32 bits, and is split up in little-endian order into 7 parts of
+ * 5 bits (the last part contains the remaining bits).
+ * 
    
+ * We convert the sequence number to unsigned 32 by adding Integer.MIN_VALUE
+ * to it. And then we reorder its bits from
+ * 66666555554444433333222221111100 to 00111112222233333444445555566666.

 /**
- * An immutable {@code HashSet} implementation that has predictable (insertion-order) iteration.
+ * Implements a mutable set using two Compressed Hash-Array Mapped Prefix-trees
+ * (CHAMP), with predictable iteration order.
+ * 
    
+ * Features:
+ * 
      
+ *     
    • supports up to 230 elements
      • 
+ *     
    • allows null elements
      • 
+ *     
    • is immutable
      • 
+ *     
    • is thread-safe
      • 
+ *     
    • iterates in the order, in which elements were inserted
      • 
+ * 
    
+ * 
    
+ * Performance characteristics:
+ * 
      
+ *     
    • copyAdd: O(1) amortized due to
+ *  *     renumbering
      • 
+ *     
    • copyRemove: O(1) amortized due to
+ *  *     renumbering
      • 
+ *     
    • contains: O(1)
      • 
+ *     
    • toMutable: O(1) + O(log N) distributed across subsequent updates in the mutable copy
      • 
+ *     
    • clone: O(1)
      • 
+ *     
    • iterator creation: O(1)
      • 
+ *     
    • iterator.next: O(1)
      • 
+ *     
    • getFirst(), getLast(): O(1)
      • 
+ * 
    
+ * 
    
+ * Implementation details:
+ * 
    
+ * This set performs read and write operations of single elements in O(1) time,
+ * and in O(1) space.
+ * 
    
+ * The CHAMP trie contains nodes that may be shared with other sets.
+ * 
    
+ * If a write operation is performed on a node, then this set creates a
+ * copy of the node and of all parent nodes up to the root (copy-path-on-write).
+ * Since the CHAMP trie has a fixed maximal height, the cost is O(1).
+ * 
    
+ * This set can create a mutable copy of itself in O(1) time and O(1) space
+ * using method {@link #toMutable()}}. The mutable copy shares its nodes
+ * with this set, until it has gradually replaced the nodes with exclusively
+ * owned nodes.
+ * 
    
+ * Insertion Order:
+ * 
    
+ * This set uses a counter to keep track of the insertion order.
+ * It stores the current value of the counter in the sequence number
+ * field of each data entry. If the counter wraps around, it must renumber all
+ * sequence numbers.
+ * 
    
+ * The renumbering is why the {@code add} and {@code remove} methods are O(1)
+ * only in an amortized sense.
+ * 
    
+ * To support iteration, a second CHAMP trie is maintained. The second CHAMP
+ * trie has the same contents as the first. However, we use the sequence number
+ * for computing the hash code of an element.
+ * 
    
+ * In this implementation, a hash code has a length of
+ * 32 bits, and is split up in little-endian order into 7 parts of
+ * 5 bits (the last part contains the remaining bits).
+ * 
    
+ * We convert the sequence number to unsigned 32 by adding Integer.MIN_VALUE
+ * to it. And then we reorder its bits from
+ * 66666555554444433333222221111100 to 00111112222233333444445555566666.

-     * A trie is a tree structure that stores a set of data objects; the
-     * path to a data object is determined by a bit sequence derived from the data
-     * object.
-     * 
    
-     * In a CHAMP trie, the bit sequence is derived from the hash code of a data
-     * object. A hash code is a bit sequence with a fixed length. This bit sequence
-     * is split up into parts. Each part is used as the index to the next child node
-     * in the tree, starting from the root node of the tree.
-     * 
    
-     * The nodes of a CHAMP trie are compressed. Instead of allocating a node for
-     * each data object, the data objects are stored directly in the ancestor node
-     * at which the path to the data object starts to become unique. This means,
-     * that in most cases, only a prefix of the bit sequence is needed for the
-     * path to a data object in the tree.
-     * 
    
-     * If the hash code of a data object in the set is not unique, then it is
-     * stored in a {@link HashCollisionNode}, otherwise it is stored in a
-     * {@link BitmapIndexedNode}. Since the hash codes have a fixed length,
-     * all {@link HashCollisionNode}s are located at the same, maximal depth
-     * of the tree.
-     * 
    
-     * In this implementation, a hash code has a length of
-     * {@value #HASH_CODE_LENGTH} bits, and is split up in little-endian order into parts of
-     * {@value #BIT_PARTITION_SIZE} bits (the last part contains the remaining bits).

-/**
- * Implements an immutable map using a Compressed Hash-Array Mapped Prefix-tree
- * (CHAMP).
- * 
    
- * Features:
- * 
      
- *     
    • supports up to 230 entries
      • 
- *     
    • allows null keys and null values
      • 
- *     
    • is immutable
      • 
- *     
    • is thread-safe
      • 
- *     
    • does not guarantee a specific iteration order
      • 
- * 
    
- * 
    
- * Performance characteristics:
- * 
      
- *     
    • copyPut: O(1)
      • 
- *     
    • copyRemove: O(1)
      • 
- *     
    • containsKey: O(1)
      • 
- *     
    • toMutable: O(1) + O(log N) distributed across subsequent updates in the mutable copy
      • 
- *     
    • clone: O(1)
      • 
- *     
    • iterator.next(): O(1)
      • 
- * 
    
- * 
    
- * Implementation details:
- * 
    
- * This map performs read and write operations of single elements in O(1) time,
- * and in O(1) space.
- * 
    
- * The CHAMP tree contains nodes that may be shared with other maps.
- * 
    
- * If a write operation is performed on a node, then this map creates a
- * copy of the node and of all parent nodes up to the root (copy-path-on-write).
- * Since the CHAMP tree has a fixed maximal height, the cost is O(1).
- * 
    
- * This map can create a mutable copy of itself in O(1) time and O(1) space
- * using method {@link #toMutable()}}. The mutable copy shares its nodes
- * with this map, until it has gradually replaced the nodes with exclusively
- * owned nodes.
- * 
    
- * All operations on this set can be performed concurrently, without a need for
- * synchronisation.

-/**
- * Implements an immutable map using two Compressed Hash-Array Mapped Prefix-trees
- * (CHAMP), with predictable iteration order.
- * 
    
- * Features:
- * 
      
- *     
    • supports up to 230 entries
      • 
- *     
    • allows null keys and null values
      • 
- *     
    • is immutable
      • 
- *     
    • is thread-safe
      • 
- *     
    • iterates in the order, in which keys were inserted
      • 
- * 
    
- * 
    
- * Performance characteristics:
- * 
      
- *     
    • copyPut, copyPutFirst, copyPutLast: O(1) amortized, due to
- *     renumbering
      • 
- *     
    • copyRemove: O(1) amortized, due to renumbering
      • 
- *     
    • containsKey: O(1)
      • 
- *     
    • toMutable: O(1) + O(log N) distributed across subsequent updates in
- *     the mutable copy
      • 
- *     
    • clone: O(1)
      • 
- *     
    • iterator creation: O(1)
      • 
- *     
    • iterator.next: O(1) with bucket sort, O(log N) with heap sort
      • 
- *     
    • getFirst, getLast: O(1)
      • 
- * 
    
- * 
    
- * Implementation details:
- * 
    
- * This map performs read and write operations of single elements in O(1) time,
- * and in O(1) space.
- * 
    
- * The CHAMP trie contains nodes that may be shared with other maps.
- * 
    
- * If a write operation is performed on a node, then this map creates a
- * copy of the node and of all parent nodes up to the root (copy-path-on-write).
- * Since the CHAMP trie has a fixed maximal height, the cost is O(1).
- * 
    
- * This map can create a mutable copy of itself in O(1) time and O(1) space
- * using method {@link #toMutable()}}. The mutable copy shares its nodes
- * with this map, until it has gradually replaced the nodes with exclusively
- * owned nodes.
- * 
    
- * All operations on this set can be performed concurrently, without a need for
- * synchronisation.
- * 
    
- * Insertion Order:
- * 
    
- * This map uses a counter to keep track of the insertion order.
- * It stores the current value of the counter in the sequence number
- * field of each data entry. If the counter wraps around, it must renumber all
- * sequence numbers.
- * 
    
- * The renumbering is why the {@code put} and {@code remove} methods are
- * O(1) only in an amortized sense.
- * 
    
- * To support iteration, a second CHAMP trie is maintained. The second CHAMP
- * trie has the same contents as the first. However, we use the sequence number
- * for computing the hash code of an element.
- * 
    
- * In this implementation, a hash code has a length of
- * 32 bits, and is split up in little-endian order into 7 parts of
- * 5 bits (the last part contains the remaining bits).
- * 
    
- * We convert the sequence number to unsigned 32 by adding Integer.MIN_VALUE
- * to it. And then we reorder its bits from
- * 66666555554444433333222221111100 to 00111112222233333444445555566666.

-/**
- * Implements a mutable set using two Compressed Hash-Array Mapped Prefix-trees
- * (CHAMP), with predictable iteration order.
- * 
    
- * Features:
- * 
      
- *     
    • supports up to 230 elements
      • 
- *     
    • allows null elements
      • 
- *     
    • is immutable
      • 
- *     
    • is thread-safe
      • 
- *     
    • iterates in the order, in which elements were inserted
      • 
- * 
    
- * 
    
- * Performance characteristics:
- * 
      
- *     
    • copyAdd: O(1) amortized due to
- *  *     renumbering
      • 
- *     
    • copyRemove: O(1) amortized due to
- *  *     renumbering
      • 
- *     
    • contains: O(1)
      • 
- *     
    • toMutable: O(1) + O(log N) distributed across subsequent updates in the mutable copy
      • 
- *     
    • clone: O(1)
      • 
- *     
    • iterator creation: O(1)
      • 
- *     
    • iterator.next: O(1)
      • 
- *     
    • getFirst(), getLast(): O(1)
      • 
- * 
    
- * 
    
- * Implementation details:
- * 
    
- * This set performs read and write operations of single elements in O(1) time,
- * and in O(1) space.
- * 
    
- * The CHAMP trie contains nodes that may be shared with other sets.
- * 
    
- * If a write operation is performed on a node, then this set creates a
- * copy of the node and of all parent nodes up to the root (copy-path-on-write).
- * Since the CHAMP trie has a fixed maximal height, the cost is O(1).
- * 
    
- * This set can create a mutable copy of itself in O(1) time and O(1) space
- * using method {@link #toMutable()}}. The mutable copy shares its nodes
- * with this set, until it has gradually replaced the nodes with exclusively
- * owned nodes.
- * 
    
- * Insertion Order:
- * 
    
- * This set uses a counter to keep track of the insertion order.
- * It stores the current value of the counter in the sequence number
- * field of each data entry. If the counter wraps around, it must renumber all
- * sequence numbers.
- * 
    
- * The renumbering is why the {@code add} and {@code remove} methods are O(1)
- * only in an amortized sense.
- * 
    
- * To support iteration, a second CHAMP trie is maintained. The second CHAMP
- * trie has the same contents as the first. However, we use the sequence number
- * for computing the hash code of an element.
- * 
    
- * In this implementation, a hash code has a length of
- * 32 bits, and is split up in little-endian order into 7 parts of
- * 5 bits (the last part contains the remaining bits).
- * 
    
- * We convert the sequence number to unsigned 32 by adding Integer.MIN_VALUE
- * to it. And then we reorder its bits from
- * 66666555554444433333222221111100 to 00111112222233333444445555566666.

+/**
+ * Represents a node in a 'Compressed Hash-Array Mapped Prefix-tree'
+ * (CHAMP) trie.
+ * 
    
+ * A trie is a tree structure that stores a set of data objects; the
+ * path to a data object is determined by a bit sequence derived from the data
+ * object.
+ * 
    
+ * In a CHAMP trie, the bit sequence is derived from the hash code of a data
+ * object. A hash code is a bit sequence with a fixed length. This bit sequence
+ * is split up into parts. Each part is used as the index to the next child node
+ * in the tree, starting from the root node of the tree.
+ * 
    
+ * The nodes of a CHAMP trie are compressed. Instead of allocating a node for
+ * each data object, the data objects are stored directly in the ancestor node
+ * at which the path to the data object starts to become unique. This means,
+ * that in most cases, only a prefix of the bit sequence is needed for the
+ * path to a data object in the tree.
+ * 
    
+ * If the hash code of a data object in the set is not unique, then it is
+ * stored in a {@link HashCollisionNode}, otherwise it is stored in a
+ * {@link BitmapIndexedNode}. Since the hash codes have a fixed length,
+ * all {@link HashCollisionNode}s are located at the same, maximal depth
+ * of the tree.
+ * 
    
+ * In this implementation, a hash code has a length of
+ * {@value #HASH_CODE_LENGTH} bits, and is split up in little-endian order into parts of
+ * {@value #BIT_PARTITION_SIZE} bits (the last part contains the remaining bits).
+ *

Subject: [PATCH 128/169] WIP: Replace internal representation of HashSet by a
 CHAMP trie.

Changes:

build.gradle
- Temporarily raises Java version from 8 to 17, because we are porting code from JHotDraw 8 which is on 17. We intend to change this back to Java 8.

ChampAbstractChampSpliterator.java,
ChampAbstractTransientChampSet.java,
ChampBitmapIndexedNode.java,
ChampChangeEvent.java,
ChampHashCollisionNode.java,
ChampIdentityObject.java,
ChampIteratorAdapter.java,
ChampListHelper.java,
ChampMutableBitmapIndexedNode.java,
ChampMutableHashCollisionNode.java,
ChampNode.java,
ChampNodeFactory.java,
ChampSequencedData.java,
ChampSequencedElement.java,
ChampSequencedEntry.java,
ChampSequencedVectorSpliterator.java,
ChampSpliterator.java,
ChampTombstone.java
- Classes with prefix "Champ" provide the CHAMP trie data structure and operations that act on it.
- Maybe we lump them all together into a ChampTrie class (similar to BitMappedTrie). However, for now, it is much easier to have separate source files for each class.

HashSet.java
- Replaces its internal representation from HashArrayMappedTrie to a CHAMP trie.
- This class extends from ChampBitmapIndexedNode rather than using composition. This helps to reduce memory usage for small collections (we save 16 bytes), and this improves the performance (we save one level of indirection).

+ * Represents a node in a 'Compressed Hash-Array Mapped Prefix-tree'
+ * (CHAMP) trie.
+ * 
    
+ * A trie is a tree structure that stores a set of data objects; the
+ * path to a data object is determined by a bit sequence derived from the data
+ * object.
+ * 
    
+ * In a CHAMP trie, the bit sequence is derived from the hash code of a data
+ * object. A hash code is a bit sequence with a fixed length. This bit sequence
+ * is split up into parts. Each part is used as the index to the next child node
+ * in the tree, starting from the root node of the tree.
+ * 
    
+ * The nodes of a CHAMP trie are compressed. Instead of allocating a node for
+ * each data object, the data objects are stored directly in the ancestor node
+ * at which the path to the data object starts to become unique. This means,
+ * that in most cases, only a prefix of the bit sequence is needed for the
+ * path to a data object in the tree.
+ * 
    
+ * If the hash code of a data object in the set is not unique, then it is
+ * stored in a {@link ChampHashCollisionNode}, otherwise it is stored in a
+ * {@link ChampBitmapIndexedNode}. Since the hash codes have a fixed length,
+ * all {@link ChampHashCollisionNode}s are located at the same, maximal depth
+ * of the tree.
+ * 
    
+ * In this implementation, a hash code has a length of
+ * {@value #HASH_CODE_LENGTH} bits, and is split up in little-endian order into parts of
+ * {@value #BIT_PARTITION_SIZE} bits (the last part contains the remaining bits).

+ * A tombstone is used by {@link VectorSet} to mark a deleted slot in its Vector.
+ * 
    
+ * A tombstone stores the minimal number of neighbors 'before' and 'after' it in the

+ * 
    
+ * When we insert a new tombstone, we update 'before' and 'after' values only on

+ * updates of up to 3 elements.
+ * 
    
+ * There are no tombstones at the first and last element of the vector. When we
+ * remove the first or last element of the vector, we remove the tombstones.
+ * 
    
+ * Example: Tombstones are shown as before.after.
+ * 
    + *
+ *

+ *
+ * Deletion of element 5:
+ * - read elements at indices 4, 5, 6                    'e' 'f' 'g'
+ * - notice that none of them are tombstones
+ * - put tombstone 0.0 at index 5                            0.0
+ *
+ * After deletion of element 5:          'a' 'b' 'c' 'd' 'e' 0.0 'g' 'h' 'i' 'j'
+ *
+ * After deletion of element 7:          'a' 'b' 'c' 'd' 'e' 0.0 'g' 0.0 'i' 'j'
+ *
+ * Deletion of element 8:
+ * - read elements at indices 7, 8, 9                                0.0 'i' 'j'
+ * - notice that 7 is a tombstone 0.0
+ * - put tombstones 0.1, 1.0 at indices 7 and 8
+ *
+ * After deletion of element 8:          'a' 'b' 'c' 'd' 'e' 0.0 'g' 0.1 1.0 'j'
+ *
+ * Deletion of element 6:
+ * - read elements at indices 5, 6, 7                        0.0 'g' 0.1
+ * - notice that two of them are tombstones

 /**
- * Implements an immutable set using a Compressed Hash-Array Mapped Prefix-tree
- * (CHAMP).
- * 
    
- * Features:
- * 
      
- *     
    • supports up to 230 elements
      • 
- *     
    • allows null elements
      • 
- *     
    • is immutable
      • 
- *     
    • is thread-safe
      • 
- *     
    • does not guarantee a specific iteration order
      • 
- * 
    
- * 
    
- * Performance characteristics:
- * 
      
- *     
    • add: O(1)
      • 
- *     
    • remove: O(1)
      • 
- *     
    • contains: O(1)
      • 
- *     
    • toMutable: O(1) + O(log N) distributed across subsequent updates in the mutable copy
      • 
- *     
    • clone: O(1)
      • 
- *     
    • iterator.next(): O(1)
      • 
- * 
    
- * 
    
- * Implementation details:
- * 
    
- * This set performs read and write operations of single elements in O(1) time,
- * and in O(1) space.
- * 
    
- * The CHAMP tree contains nodes that may be shared with other sets.
- * 
    
- * If a write operation is performed on a node, then this set creates a
- * copy of the node and of all parent nodes up to the root (copy-path-on-write).
- * Since the CHAMP tree has a fixed maximal height, the cost is O(1).
- * 
    
- * This set can create a mutable copy of itself in O(1) time and O(1) space
- * using method {@code #toMutable()}}. The mutable copy shares its nodes
- * with this set, until it has gradually replaced the nodes with exclusively
- * owned nodes.
- *

Subject: [PATCH 131/169] WIP: Replace internal representation of HashMap by a
 CHAMP trie.

Changes:

HashMap.java
- Replaces its internal representation from HashArrayMappedTrie to a CHAMP trie.

ChampChangeEvent.java
- Adds method isAdded().

HashSet.java
- Adds javadoc.
- Renames method updateFunction to updateElement.

HashMapTest.java
- Changes the expected result of 2 unit tests. I believe, that the test expectations were wrong.

 /**
- * An immutable {@code HashSet} implementation.
+ * Implements an immutable set using a Compressed Hash-Array Mapped Prefix-tree
+ * (CHAMP).
+ * 
      
+ * Features:
+ * 
        
+ *     
      • supports up to 230 entries
        • 
+ *     
      • allows null elements
        • 
+ *     
      • is immutable
        • 
+ *     
      • is thread-safe
        • 
+ *     
      • does not guarantee a specific iteration order
        • 
+ * 
      
+ * 
      
+ * Performance characteristics:
+ * 
        
+ *     
      • add: O(1)
        • 
+ *     
      • remove: O(1)
        • 
+ *     
      • contains: O(1)
        • 
+ *     
      • toMutable: O(1) + O(log N) distributed across subsequent updates in the mutable copy
        • 
+ *     
      • clone: O(1)
        • 
+ *     
      • iterator.next(): O(1)
        • 
+ * 
      
+ * 
      
+ * Implementation details:
+ * 
      
+ * This set performs read and write operations of single elements in O(1) time,
+ * and in O(1) space.
+ * 
      
+ * The CHAMP trie contains nodes that may be shared with other sets.
+ * 
      
+ * If a write operation is performed on a node, then this set creates a
+ * copy of the node and of all parent nodes up to the root (copy-path-on-write).
+ * Since the CHAMP trie has a fixed maximal height, the cost is O(1).
+ * 
      
+ * The immutable version of this set extends from the non-public class
+ * {@code ChampBitmapIndexNode}. This design safes 16 bytes for every instance,
+ * and reduces the number of redirections for finding an element in the
+ * collection by 1.
+ * 
      
+ * References:
+ * 
      
+ * Portions of the code in this class have been derived from 'The Capsule Hash Trie Collections Library', and from
+ * 'JHotDraw 8'.

 /**
- * Implements an immutable map using two Compressed Hash-Array Mapped Prefix-trees
- * (CHAMP), with predictable iteration order.
- * 
      
- * Features:
- * 
        
- *     
      • supports up to 230 entries
        • 
- *     
      • allows null keys and null values
        • 
- *     
      • is immutable
        • 
- *     
      • is thread-safe
        • 
- *     
      • iterates in the order, in which keys were inserted
        • 
- * 
      
- * 
      
- * Performance characteristics:
- * 
        
- *     
      • copyPut, copyPutFirst, copyPutLast: O(1) amortized, due to
- *     renumbering
        • 
- *     
      • copyRemove: O(1) amortized, due to renumbering
        • 
- *     
      • containsKey: O(1)
        • 
- *     
      • toMutable: O(1) + O(log N) distributed across subsequent updates in
- *     the mutable copy
        • 
- *     
      • clone: O(1)
        • 
- *     
      • iterator creation: O(1)
        • 
- *     
      • iterator.next: O(1) with bucket sort, O(log N) with heap sort
        • 
- *     
      • getFirst, getLast: O(1)
        • 
- * 
      
- * 
      
- * Implementation details:
- * 
      
- * This map performs read and write operations of single elements in O(1) time,
- * and in O(1) space.
- * 
      
- * The CHAMP trie contains nodes that may be shared with other maps.
- * 
      
- * If a write operation is performed on a node, then this map creates a
- * copy of the node and of all parent nodes up to the root (copy-path-on-write).
- * Since the CHAMP trie has a fixed maximal height, the cost is O(1).
- * 
      
- * This map can create a mutable copy of itself in O(1) time and O(1) space
- * using method {@link #toMutable()}}. The mutable copy shares its nodes
- * with this map, until it has gradually replaced the nodes with exclusively
- * owned nodes.
- * 
      
- * All operations on this set can be performed concurrently, without a need for
- * synchronisation.
- * 
      
- * Insertion Order:
- * 
      
- * This map uses a counter to keep track of the insertion order.
- * It stores the current value of the counter in the sequence number
- * field of each data entry. If the counter wraps around, it must renumber all
- * sequence numbers.
- * 
      
- * The renumbering is why the {@code put} and {@code remove} methods are
- * O(1) only in an amortized sense.
- * 
      
- * To support iteration, a second CHAMP trie is maintained. The second CHAMP
- * trie has the same contents as the first. However, we use the sequence number
- * for computing the hash code of an element.
- * 
      
- * In this implementation, a hash code has a length of
- * 32 bits, and is split up in little-endian order into 7 parts of
- * 5 bits (the last part contains the remaining bits).
- * 
      
- * We convert the sequence number to unsigned 32 by adding Integer.MIN_VALUE
- * to it. And then we reorder its bits from
- * 66666555554444433333222221111100 to 00111112222233333444445555566666.

- * To support iteration, a second CHAMP trie is maintained. The second CHAMP
- * trie has the same contents as the first. However, we use the sequence number
- * for computing the hash code of an element.
+ * To support iteration, we use a Vector. The Vector has the same contents
+ * as the CHAMP trie. However, its elements are stored in insertion order.
  * 
        
- * In this implementation, a hash code has a length of
- * 32 bits, and is split up in little-endian order into 7 parts of
- * 5 bits (the last part contains the remaining bits).
+ * If an element is removed from the CHAMP trie that is not the first or the
+ * last element of the Vector, we replace its corresponding element in
+ * the Vector by a tombstone. If the element is at the start or end of the Vector,
+ * we remove the element and all its neighboring tombstones from the Vector.
  * 
        
- * We convert the sequence number to unsigned 32 by adding Integer.MIN_VALUE
- * to it. And then we reorder its bits from
- * 66666555554444433333222221111100 to 00111112222233333444445555566666.
+ * A tombstone can store the number of neighboring tombstones in ascending and in descending
+ * direction. We use these numbers to skip tombstones when we iterate over the vector.
+ * Since we only allow iteration in ascending or descending order from one of the ends of
+ * the vector, we do not need to keep the number of neighbors in all tombstones up to date.
+ * It is sufficient, if we update the neighbor with the lowest index and the one with the
+ * highest index.
+ * 
        
+ * If the number of tombstones exceeds half of the size of the collection, we renumber all
+ * sequence numbers, and we create a new Vector.
+ * 
        
+ * The immutable version of this set extends from the non-public class
+ * {@code ChampBitmapIndexNode}. This design safes 16 bytes for every instance,
+ * and reduces the number of redirections for finding an element in the
+ * collection by 1.

- * An immutable {@code LinkedHashMap} implementation that has predictable (insertion-order) iteration.
+ * Implements an immutable map using a Compressed Hash-Array Mapped Prefix-tree
+ * (CHAMP) and a bit-mapped trie (Vector).
+ * 
        
+ * Features:
+ * 
          
+ *     
        • supports up to 230 entries
          • 
+ *     
        • allows null keys and null values
          • 
+ *     
        • is immutable
          • 
+ *     
        • is thread-safe
          • 
+ *     
        • iterates in the order, in which keys were inserted
          • 
+ * 
        
+ * 
        
+ * Performance characteristics:
+ * 
          
+ *     
        • put, putFirst, putLast: O(log N) in an amortized sense, because we sometimes have to
+ *     renumber the elements.
          • 
+ *     
        • remove: O(log N) in an amortized sense, because we sometimes have to renumber the elements.
          • 
+ *     
        • containsKey: O(1)
          • 
+ *     
        • toMutable: O(1) + O(log N) distributed across subsequent updates in
+ *     the mutable copy

        • getFirst, getLast: O(log N)
          • 
+ * 
        
+ * 
        
+ * Implementation details:
+ * 
        
+ * This map performs read and write operations of single elements in O(log N) time,
+ * and in O(log N) space, where N is the number of elements in the set.
+ * 
        
+ * The CHAMP trie contains nodes that may be shared with other maps.
+ * 
        
+ * If a write operation is performed on a node, then this set creates a
+ * copy of the node and of all parent nodes up to the root (copy-path-on-write).
+ * Since the CHAMP trie has a fixed maximal height, the cost is O(1).
+ * 
        
+ * Insertion Order:
+ * 
        
+ * This map uses a counter to keep track of the insertion order.
+ * It stores the current value of the counter in the sequence number
+ * field of each data entry. If the counter wraps around, it must renumber all
+ * sequence numbers.
+ * 
        
+ * The renumbering is why the {@code add} and {@code remove} methods are O(1)
+ * only in an amortized sense.
+ * 
        
+ * To support iteration, we use a Vector. The Vector has the same contents
+ * as the CHAMP trie. However, its elements are stored in insertion order.
+ * 
        
+ * If an element is removed from the CHAMP trie that is not the first or the
+ * last element of the Vector, we replace its corresponding element in
+ * the Vector by a tombstone. If the element is at the start or end of the Vector,
+ * we remove the element and all its neighboring tombstones from the Vector.
+ * 
        
+ * A tombstone can store the number of neighboring tombstones in ascending and in descending
+ * direction. We use these numbers to skip tombstones when we iterate over the vector.
+ * Since we only allow iteration in ascending or descending order from one of the ends of
+ * the vector, we do not need to keep the number of neighbors in all tombstones up to date.
+ * It is sufficient, if we update the neighbor with the lowest index and the one with the
+ * highest index.
+ * 
        
+ * If the number of tombstones exceeds half of the size of the collection, we renumber all
+ * sequence numbers, and we create a new Vector.
+ * 
        
+ * The immutable version of this set extends from the non-public class
+ * {@code ChampBitmapIndexNode}. This design safes 16 bytes for every instance,
+ * and reduces the number of redirections for finding an element in the
+ * collection by 1.

Subject: [PATCH 137/169] Add benchmarks. There appears to be a bug in
 transient 'update' methods in CHAMP trie nodes, because it is not faster than
 non-transient 'update'. Transient 'remove' in CHAMP trie nodes is faster than
 the non-transient 'remove' - so that seems to be correct.

-/**
- * Implements a mutable map using a Compressed Hash-Array Mapped Prefix-tree
- * (CHAMP).
- * 
        
- * Features:
- * 
          
- *     
        • supports up to 230 entries
          • 
- *     
        • allows null keys and null values
          • 
- *     
        • is mutable
          • 
- *     
        • is not thread-safe
          • 
- *     
        • does not guarantee a specific iteration order
          • 
- * 
        
- * 
        
- * Performance characteristics:
- * 
          
- *     
        • put: O(1)
          • 
- *     
        • remove: O(1)
          • 
- *     
        • containsKey: O(1)
          • 
- *     
        • toImmutable: O(1) + O(log N) distributed across subsequent updates in
- *     this map
          • 
- *     
        • clone: O(1) + O(log N) distributed across subsequent updates in this
- *     map and in the clone
          • 
- *     
        • iterator.next: O(1)
          • 
- * 
        
- * 
        
- * Implementation details:
- * 
        
- * This map performs read and write operations of single elements in O(1) time,
- * and in O(1) space.
- * 
        
- * The CHAMP tree contains nodes that may be shared with other maps, and nodes
- * that are exclusively owned by this map.
- * 
        
- * If a write operation is performed on an exclusively owned node, then this
- * map is allowed to mutate the node (mutate-on-write).
- * If a write operation is performed on a potentially shared node, then this
- * map is forced to create an exclusive copy of the node and of all not (yet)
- * exclusively owned parent nodes up to the root (copy-path-on-write).
- * Since the CHAMP tree has a fixed maximal height, the cost is O(1) in either
- * case.
- * 
        
- * This map can create an immutable copy of itself in O(1) time and O(1) space
- * using method {@link #toImmutable()}. This map loses exclusive ownership of
- * all its tree nodes.
- * Thus, creating an immutable copy increases the constant cost of
- * subsequent writes, until all shared nodes have been gradually replaced by
- * exclusively owned nodes again.
- *

-/**
- * Implements a mutable set using a Compressed Hash-Array Mapped Prefix-tree
- * (CHAMP).
- * 
        
- * Features:
- * 
          
- *     
        • supports up to 230 elements
          • 
- *     
        • allows null elements
          • 
- *     
        • is mutable
          • 
- *     
        • is not thread-safe
          • 
- *     
        • does not guarantee a specific iteration order
          • 
- * 
        
- * 
        
- * Performance characteristics:
- * 
          
- *     
        • add: O(1)
          • 
- *     
        • remove: O(1)
          • 
- *     
        • contains: O(1)
          • 
- *     
        • toImmutable: O(1) + O(log N) distributed across subsequent updates in
- *     this set
          • 
- *     
        • clone: O(1) + O(log N) distributed across subsequent updates in this
- *     set and in the clone
          • 
- *     
        • iterator.next: O(1)
          • 
- * 
        
- * 
        
- * Implementation details:
- * 
        
- * This set performs read and write operations of single elements in O(1) time,
- * and in O(1) space.
- * 
        
- * The CHAMP tree contains nodes that may be shared with other sets, and nodes
- * that are exclusively owned by this set.
- * 
        
- * If a write operation is performed on an exclusively owned node, then this
- * set is allowed to mutate the node (mutate-on-write).
- * If a write operation is performed on a potentially shared node, then this
- * set is forced to create an exclusive copy of the node and of all not (yet)
- * exclusively owned parent nodes up to the root (copy-path-on-write).
- * Since the CHAMP tree has a fixed maximal height, the cost is O(1) in either
- * case.
- * 
        
- * This set can create an immutable copy of itself in O(1) time and O(1) space
- * using method {@link #toImmutable()}. This set loses exclusive ownership of
- * all its tree nodes.
- * Thus, creating an immutable copy increases the constant cost of
- * subsequent writes, until all shared nodes have been gradually replaced by
- * exclusively owned nodes again.
- * 
        
- * Note that this implementation is not synchronized.
- * If multiple threads access this set concurrently, and at least
- * one of the threads modifies the set, it must be synchronized
- * externally.  This is typically accomplished by synchronizing on some
- * object that naturally encapsulates the set.

- * Implements a mutable map using two Compressed Hash-Array Mapped Prefix-trees

- *     
        • supports up to 230 entries
          • 
- *     
        • allows null keys and null values

- *

- *

          • 
- * 
        
- * 
        
- * Performance characteristics:
- * 
          
- *     
        • put, putFirst, putLast: O(1) amortized, due to renumbering
          • 
- *     
        • remove: O(1) amortized, due to renumbering
          • 
- *

- *     this mutable map

- *     
        • clone: O(1) + O(log N) distributed across subsequent updates in this
- *     mutable map and in the clone
          • 
- *     
        • iterator creation: O(1)
          • 
- *     
        • iterator.next: O(1) with bucket sort, O(log N) with heap sort
          • 
- *     
        • getFirst, getLast: O(1)
          • 
- * 
        
- * 
        
- * Implementation details:
- * 
        
- * This map performs read and write operations of single elements in O(1) time,
- * and in O(1) space.
- * 
        
- * The CHAMP trie contains nodes that may be shared with other maps, and nodes
- * that are exclusively owned by this map.
- * 
        
- * If a write operation is performed on an exclusively owned node, then this
- * map is allowed to mutate the node (mutate-on-write).
- * If a write operation is performed on a potentially shared node, then this
- * map is forced to create an exclusive copy of the node and of all not (yet)
- * exclusively owned parent nodes up to the root (copy-path-on-write).
- * Since the CHAMP trie has a fixed maximal height, the cost is O(1) in either
- * case.
- * 
        
- * This map can create an immutable copy of itself in O(1) time and O(1) space
- * using method {@link #toImmutable()}. This map loses exclusive ownership of
- * all its tree nodes.
- * Thus, creating an immutable copy increases the constant cost of
- * subsequent writes, until all shared nodes have been gradually replaced by
- * exclusively owned nodes again.
- * 
        
- * Insertion Order:
- * 
        
- * This map uses a counter to keep track of the insertion order.
- * It stores the current value of the counter in the sequence number
- * field of each data entry. If the counter wraps around, it must renumber all
- * sequence numbers.
- * 
        
- * The renumbering is why the {@code put} and {@code remove} methods are
- * O(1) only in an amortized sense.
- * 
        
- * To support iteration, a second CHAMP trie is maintained. The second CHAMP
- * trie has the same contents as the first. However, we use the sequence number
- * for computing the hash code of an element.
- * 
        
- * In this implementation, a hash code has a length of
- * 32 bits, and is split up in little-endian order into 7 parts of
- * 5 bits (the last part contains the remaining bits).
- * 
        
- * We convert the sequence number to unsigned 32 by adding Integer.MIN_VALUE
- * to it. And then we reorder its bits from
- * 66666555554444433333222221111100 to 00111112222233333444445555566666.

-/**
- * Implements a mutable set using a Compressed Hash-Array Mapped Prefix-tree
- * (CHAMP), with predictable iteration order.
- * 
        
- * Features:
- * 
          
- *     
        • supports up to 230 elements
          • 
- *     
        • allows null elements
          • 
- *     
        • is mutable
          • 
- *     
        • is not thread-safe
          • 
- *     
        • iterates in the order, in which elements were inserted
          • 
- * 
        
- * 
        
- * Performance characteristics:
- * 
          
- *     
        • add: O(1) amortized
          • 
- *     
        • remove: O(1)
          • 
- *     
        • contains: O(1)
          • 
- *     
        • toImmutable: O(1) + O(log N) distributed across subsequent updates in
- *     this set
          • 
- *     
        • clone: O(1) + O(log N) distributed across subsequent updates in this
- *     set and in the clone
          • 
- *     
        • iterator creation: O(1)
          • 
- *     
        • iterator.next: O(1) with bucket sort, O(log N) with heap sort
          • 
- *     
        • getFirst, getLast: O(1)
          • 
- * 
        
- * 
        
- * Implementation details:
- * 
        
- * This set performs read and write operations of single elements in O(1) time,
- * and in O(1) space.
- * 
        
- * The CHAMP trie contains nodes that may be shared with other sets, and nodes
- * that are exclusively owned by this set.
- * 
        
- * If a write operation is performed on an exclusively owned node, then this
- * set is allowed to mutate the node (mutate-on-write).
- * If a write operation is performed on a potentially shared node, then this
- * set is forced to create an exclusive copy of the node and of all not (yet)
- * exclusively owned parent nodes up to the root (copy-path-on-write).
- * Since the CHAMP trie has a fixed maximal height, the cost is O(1) in either
- * case.
- * 
        
- * This set can create an immutable copy of itself in O(1) time and O(1) space
- * using method {@link #toImmutable()}. This set loses exclusive ownership of
- * all its tree nodes.
- * Thus, creating an immutable copy increases the constant cost of
- * subsequent writes, until all shared nodes have been gradually replaced by
- * exclusively owned nodes again.
- * 
        
- * Insertion Order:
- * 
        
- * This set uses a counter to keep track of the insertion order.
- * It stores the current value of the counter in the sequence number
- * field of each data entry. If the counter wraps around, it must renumber all
- * sequence numbers.
- * 
        
- * The renumbering is why the {@code add} is O(1) only in an amortized sense.
- * 
        
- * To support iteration, a second CHAMP trie is maintained. The second CHAMP
- * trie has the same contents as the first. However, we use the sequence number
- * for computing the hash code of an element.
- * 
        
- * In this implementation, a hash code has a length of
- * 32 bits, and is split up in little-endian order into 7 parts of
- * 5 bits (the last part contains the remaining bits).
- * 
        
- * We convert the sequence number to unsigned 32 by adding Integer.MIN_VALUE
- * to it. And then we reorder its bits from
- * 66666555554444433333222221111100 to 00111112222233333444445555566666.
- * 
        
- * Note that this implementation is not synchronized.
- * If multiple threads access this set concurrently, and at least
- * one of the threads modifies the set, it must be synchronized
- * externally.  This is typically accomplished by synchronizing on some
- * object that naturally encapsulates the set.

- * Represents a node in a 'Compressed Hash-Array Mapped Prefix-tree'

- * 
        
- * A trie is a tree structure that stores a set of data objects; the
- * path to a data object is determined by a bit sequence derived from the data
- * object.
- * 
        
- * In a CHAMP trie, the bit sequence is derived from the hash code of a data
- * object. A hash code is a bit sequence with a fixed length. This bit sequence
- * is split up into parts. Each part is used as the index to the next child node
- * in the tree, starting from the root node of the tree.
- * 
        
- * The nodes of a CHAMP trie are compressed. Instead of allocating a node for
- * each data object, the data objects are stored directly in the ancestor node
- * at which the path to the data object starts to become unique. This means,
- * that in most cases, only a prefix of the bit sequence is needed for the
- * path to a data object in the tree.
- * 
        
- * If the hash code of a data object in the set is not unique, then it is
- * stored in a {@link HashCollisionNode}, otherwise it is stored in a
- * {@link BitmapIndexedNode}. Since the hash codes have a fixed length,
- * all {@link HashCollisionNode}s are located at the same, maximal depth
- * of the tree.
- * 
        
- * In this implementation, a hash code has a length of
- * {@value #HASH_CODE_LENGTH} bits, and is split up in little-endian order into parts of
- * {@value #BIT_PARTITION_SIZE} bits (the last part contains the remaining bits).

- * Represents a node in a 'Compressed Hash-Array Mapped Prefix-tree'
- * (CHAMP) trie.
- * 
        
- * A trie is a tree structure that stores a set of data objects; the
- * path to a data object is determined by a bit sequence derived from the data
- * object.
- * 
        
- * In a CHAMP trie, the bit sequence is derived from the hash code of a data
- * object. A hash code is a bit sequence with a fixed length. This bit sequence
- * is split up into parts. Each part is used as the index to the next child node
- * in the tree, starting from the root node of the tree.
- * 
        
- * The nodes of a CHAMP trie are compressed. Instead of allocating a node for
- * each data object, the data objects are stored directly in the ancestor node
- * at which the path to the data object starts to become unique. This means,
- * that in most cases, only a prefix of the bit sequence is needed for the
- * path to a data object in the tree.
- * 
        
- * If the hash code of a data object in the set is not unique, then it is
- * stored in a {@link ChampHashCollisionNode}, otherwise it is stored in a
- * {@link ChampBitmapIndexedNode}. Since the hash codes have a fixed length,
- * all {@link ChampHashCollisionNode}s are located at the same, maximal depth
- * of the tree.
- * 
        
- * In this implementation, a hash code has a length of
- * {@value #HASH_CODE_LENGTH} bits, and is split up in little-endian order into parts of
- * {@value #BIT_PARTITION_SIZE} bits (the last part contains the remaining bits).
- *

-/**
- * A tombstone is used by {@code VectorSet} to mark a deleted slot in its Vector.
- * 
        
- * A tombstone stores the minimal number of neighbors 'before' and 'after' it in the
- * Vector.
- * 
        
- * When we insert a new tombstone, we update 'before' and 'after' values only on
- * the first and last tombstone of a sequence of tombstones. Therefore, a delete
- * operation requires reading of up to 3 neighboring elements in the vector, and
- * updates of up to 3 elements.
- * 
        
- * There are no tombstones at the first and last element of the vector. When we
- * remove the first or last element of the vector, we remove the tombstones.
- * 
        
- * Example: Tombstones are shown as before.after.
- * 
        - *
- *
- *                              Indices:  0   1   2   3   4   5   6   7   8   9
- * Initial situation:           Values:  'a' 'b' 'c' 'd' 'e' 'f' 'g' 'h' 'i' 'j'
- *
- * Deletion of element 5:
- * - read elements at indices 4, 5, 6                    'e' 'f' 'g'
- * - notice that none of them are tombstones
- * - put tombstone 0.0 at index 5                            0.0
- *
- * After deletion of element 5:          'a' 'b' 'c' 'd' 'e' 0.0 'g' 'h' 'i' 'j'
- *
- * After deletion of element 7:          'a' 'b' 'c' 'd' 'e' 0.0 'g' 0.0 'i' 'j'
- *
- * Deletion of element 8:
- * - read elements at indices 7, 8, 9                                0.0 'i' 'j'
- * - notice that 7 is a tombstone 0.0
- * - put tombstones 0.1, 1.0 at indices 7 and 8
- *
- * After deletion of element 8:          'a' 'b' 'c' 'd' 'e' 0.0 'g' 0.1 1.0 'j'
- *
- * Deletion of element 6:
- * - read elements at indices 5, 6, 7                        0.0 'g' 0.1
- * - notice that two of them are tombstones
- * - put tombstones 0.3, 0.0, 3.0 at indices 5, 6 and 8
- *
- * After deletion of element 6:          'a' 'b' 'c' 'd' 'e' 0.3 0.0 0.1 3.0 'j'
- *
- * Deletion of the last element 9:
- * - read elements at index 8                                            3.0
- * - notice that it is a tombstone
- * - remove the last element and the neighboring tombstone sequence

+     * Represents a node in a 'Compressed Hash-Array Mapped Prefix-tree'
+     * (CHAMP) trie.
+     * 
        
+     * A trie is a tree structure that stores a set of data objects; the
+     * path to a data object is determined by a bit sequence derived from the data
+     * object.
+     * 
        
+     * In a CHAMP trie, the bit sequence is derived from the hash code of a data
+     * object. A hash code is a bit sequence with a fixed length. This bit sequence
+     * is split up into parts. Each part is used as the index to the next child node
+     * in the tree, starting from the root node of the tree.
+     * 
        
+     * The nodes of a CHAMP trie are compressed. Instead of allocating a node for
+     * each data object, the data objects are stored directly in the ancestor node
+     * at which the path to the data object starts to become unique. This means,
+     * that in most cases, only a prefix of the bit sequence is needed for the
+     * path to a data object in the tree.
+     * 
        
+     * If the hash code of a data object in the set is not unique, then it is
+     * stored in a {@link HashCollisionNode}, otherwise it is stored in a
+     * {@link BitmapIndexedNode}. Since the hash codes have a fixed length,
+     * all {@link HashCollisionNode}s are located at the same, maximal depth
+     * of the tree.
+     *

+vavr-champ is binary compatible with the vavr library, but uses CHAMP-based collections internally.
 
-
        
-  Vavr's custom image
-
        
+For more details see the [JavaDoc](https://www.randelshofer.ch/vavr/javadoc/):
 
-Vavr is an object-functional language extension to Java 8 that aims to reduce the number of lines of code and increase code quality.
-It provides persistent collections, functional abstractions for error handling, concurrent programming, pattern matching, and much more.
+- [HashMap](https://www.randelshofer.ch/vavr/javadoc/io/vavr/collection/HashMap.html)
 
-Vavr fuses the power of object-oriented programming with the elegance and robustness of functional programming.
-The most interesting part is a feature-rich, persistent collection library that smoothly integrates with Java's standard collections.
+- [HashSet](https://www.randelshofer.ch/vavr/javadoc/io/vavr/collection/HashSet.html
+  )
 
-Because Vavr does not depend on any libraries (other than the JVM), you can easily add it as a standalone .jar to your classpath.
+- [LinkedHashMap](https://www.randelshofer.ch/vavr/javadoc/io/vavr/collection/LinkedHashMap.html)
 
-### Stargazers over time
-[![Stargazers over time](https://starchart.cc/vavr-io/vavr.svg?variant=adaptive)](https://starchart.cc/vavr-io/vavr)
+- [LinkedHashSet](https://www.randelshofer.ch/vavr/javadoc/io/vavr/collection/LinkedHashSet.html)
 
+To use it instead of the original `vavr` library, you can specify `vavr-champ` as your dependency.
 
-## Using Vavr
+Maven:
 
-See [User Guide](http://docs.vavr.io) and/or [Javadoc](http://www.javadoc.io/doc/io.vavr/vavr).

-## Status
+[![vavr-logo](https://user-images.githubusercontent.com/743833/62367542-486f0500-b52a-11e9-815e-e9788d4c8c8d.png)](http://vavr.io/)
 
-This is an experimental fork of [github.com/vavr-io/vavr](https://github.com/vavr-io/vavr).
+Vavr is an object-functional language extension to Java 8, which aims to reduce the lines of code and increase code
+quality.
+It provides persistent collections, functional abstractions for error handling, concurrent programming, pattern matching
+and much more.
 
-## CHAMP collections
+Vavr fuses the power of object-oriented programming with the elegance and robustness of functional programming.
+The most interesting part is a feature-rich, persistent collection library that smoothly integrates with Java's standard
+collections.
 
-This fork contains additional collections, that use
-CHAMP (Compressed Hash-Array Mapped Prefix-tree) as their underlying data structures.
-The collections are derived from [github.com/usethesource/capsule](https://github.com/usethesource/capsule),
-and [github.com/wrandelshofer/jhotdraw8](https://github.com/wrandelshofer/jhotdraw8).
+Because Vavr does not depend on any libraries (other than the JVM) you can easily add it as standalone .jar to your
+classpath.
 
-The collections are:
+To stay up to date please follow the [blog](http://blog.vavr.io).
 
-* ChampSet
-* ChampMap
-* SequencedChampSet
-* SequencedChampMap
+## Using Vavr
 
-Each collection has a mutable partner:
+See [User Guide](http://docs.vavr.io) and/or [Javadoc](http://www.javadoc.io/doc/io.vavr/vavr).
 
-* MutableChampSet
-* MutableChampMap
-* MutableSequencedChampSet
-* MutableSequencedChampMap
+### Gradle tasks:
 
-## Performance characteristics
+* Build: `./gradlew check`
+  * test reports: `./build/reports/tests/test/index.html`
+  * coverage reports: `./build/reports/jacoco/test/html/index.html`
+* Javadoc (linting): `./gradlew javadoc`
 
-### ChampSet, ChampMap, MutableChampSet, MutableChampMap:
-
-* Maximal supported size: 230 elements.
-* Get/Insert/Remove: O(1)
-* Head/Tail: O(1)
-* Iterator creation: O(1)
-* Iterator.next(): O(1)
-* toImmutable/toMutable: O(1) + a cost distributed across subsequent updates of the mutable copy
-
-The costs are only constant in the limit. In practice, they are more like
-O(log32 N).
-
-If a collection is converted from/to immutable/mutable, the mutual copy
-of the collection loses ownership of all its trie nodes. Updates are slightly
-more expensive for the mutable copy, until it gains exclusive ownership of all trie
-nodes again.
-
-### SequencedChampSet, SequencedChampMap, MutableSequencedChampSet, MutableSequencedChampMap:
-
-* Maximal supported size: 230 elements.
-* Get/Insert/Remove: O(1) amortized
-* Head/Tail: O(1)
-* Iterator creation: O(1)
-* Iterator.next(): O(1)
-* toImmutable/toMutable: O(1) + a cost distributed across subsequent updates of the mutable copy
-
-The collections store a sequence number with each data element, and they maintain
-a second CHAMP trie, that is indexed by the sequence number.
-The sequence numbers must be renumbered from time to time, to prevent
-large gaps and overflows/underflows.
-
-To support iteration over the elements, we maintain a second CHAMP trie, which
-uses the sequence number as the key to the elements.
-
-
-## Benchmarks
-
-The following chart shows a comparison of the CHAMP maps with vavr collections
-and with Scala collections. Scala org.scala-lang:scala-library:2.13.10 was used.
-
-The collections have 1 million entries.
-
-The y-axis is labeled in nanoseconds. The bars are cut off at 1'500 ns (!).
-This cuts off the elapsed times of functions that run in linear times.
-
-![](BenchmarkChart.png)
-
-* **scala.HashMap**
    
-  Uses a CHAMP trie as its underlying data structure.
    
-  Performs all operations in constant time.
    
-  Iterates in an unspecified sequence.
    
-  This is the fastest implementation except for the contains() operation.
-* **scala.VectorMap** 
    
-  Uses a CHAMP trie and a radix-balanced finger tree (Vector) as its
-  underlying data structures.
    
-  Performs all operations in amortised constant time.
    
-  Iterates in the sequence in which the entries were inserted in the map.
    
-  May hog memory, because deleted elements are replaced by tomb stone objects.
    
-  This is one of the fastest implementation except for iteration.
-* **scala.TreeSeqMap** 
    
-  Uses a CHAMP trie and a red-black tree as its underlying data structures.
    
-  Performs all operations in amortised constant time.
    
-  Iterates in the sequence in which the entries were inserted in the map.
    
-  This is one of the slowest implementations.
-* **vavr.HashMap**
    
-  Uses a HAMP trie as its underlying data structure.
    
-  Performs all operations in constant time.
    
-  This is one of the fastest implementations.
-* **vavr.LinkedHashMap** 
    
-  Uses a HAMP trie and a Banker's queue as its underlying data structure.
    
-  Performs some operations in constant time and some in linear time.
    
-  Iterates in the sequence in which the entries were inserted in the map.
    
-  This implementation is the fastest for read operations, but the
-  slowest for update operations.
-* **vavr.ChampMap** 
    
-  Uses a CHAMP trie as its underlying data structure.
    
-  Performs all operations in constant time.
    
-  Iterates in an unspecified sequence.
    
-* **vavr.SequencedChampMap**
    
-  Uses two CHAMP tries as its underlying data structures.
    
-  Performs all operations in amortised constant time.
    
-  Iterates in the sequence in which the entries were inserted in the map.
    
-  This class has the same design trade-offs like scala.TreeSeqMap.
    
-  This is one of the slower implementations - it beats scala.TreeSeqMap
-  except for head() and tail() operations.
